It also provides a state-of-the-art analysis of the theories of integration and differentiation of functions in the late eighteenth century, as well as one of the first uses of determinants to solve systems of linear equations. Thus such a method which is not practical anyway, given the very large number of computations it requires, even in simple cases leads to useless computations. Unfortunately, it does not lend itself well to random browsing, at least not at first. In addition, there is nothing available to recognize superfluous factors, which appear only in the last equation. Translator's Foreword xi Dedication from the 1779 edition xiii Preface to the 1779 edition xv Introduction: Theory of differences and sums of quantities 1 Definitions and preliminary notions 1 About the way to determine the differences of quantities 3 A general and fundamental remark 7 Reductions that may apply to the general rule to differentiate quantities when several differentiations must be made. These functions could provide fewer, as many, or more coefficients than are necessary to remove the terms to be eliminated.

Gillespie, New York: Scribner, 1972, vol. Various other very distinguished Analysts have dealt with this problem since then, but they focused their attention on simplifying computations and making their results more insightful with respect to the general properties of these kinds of equations. . Infinitesimal analysis was considered so attractive and important because of its numerous and useful applications; as such it attracted upon itself all research attention and efforts. The solution to this first question gave me insight as to how I should approach the problem of finding the degree of the final equation resulting from an arbitrary number of complete equations, of arbitrary degrees and having the same number of unknowns. Bix, Robert, , 2 nd ed.

It was also translated into English by John Farrar of Harvard University. The enormous complexity of the calculations necessary for successive variable eliminations is probably one of the reasons for which no general result may be found in the written works of the analysts, when dealing with equations involving more than two unknowns, except in the case of linear equations. Thus, and in spite of the degree of perfection reached in solving equations in two unknowns, analysis still lacked tools for systems involving large numbers of equations and unknowns. Since then, the King gave you a much wider ranging assignment: This important mission proves, Monseigneur, that the same spirit can make significant contributions to very different missions. And where the unknowns, combined two-by-two, three-by-three, four-by-four etc. He is also an Adviser to the French Academy of Technologies. Starting from known methods, analysts may have been discouraged from making any significant progress in this area.

His main push was devoted to determining the degree of the final equation in one unknown, resulting from the original set of polynomial equations. Book Two In which we give a process for reaching the final equation resulting from an arbitrary number of equations in the same number of unknowns, and in which we present many general properties of algebraic quantities and equations General observations 194. In appearance, it would seem that little remains to be said about this matter, since we know of methods that lead us quickly to the value of all unknowns in first-order equations. Let us now pause and look at the state of the art when we started the work presented here. Polynomial multiplier methods have become, today, one of the most promising approaches to solving complex systems of polynomial equations or inequalities, and this translation offers a valuable historic perspective on this active research field.

We further assume that the degrees of the n - 3 other unknowns do not exceed given values; we also assume that the combination of two, three, four, etc. Indeed, assume we multiply any of these equations by a complete polynomial of undetermined order; in addition, assume that we use all the remaining equations to cancel some terms in the polynomial multiplier; then, by the same token, we can cancel some terms in the product equation. As a result of these analyses, I felt even more how imperfect the analysis was, and I thought it would be useful to develop a method that would be free of these defects. About the care to be exercised when using simpler polynomial multipliers than their general form 231 and following , when dealing with incomplete equations More applications, etc. We further assume that the degrees of the n - 3 other unknowns do not exceed given values; we also assume that the combination of two, three, four, etc. His interests span numerical analysis, optimization, systems analysis, and their applications to aerospace engineering. What insight can such a method provide about the general properties of the proposed equations? New observations about the factors of the final equation 333.

Christine-Marie Feron and Jacques Pedron have offered me constant support and understanding during the many evenings I spent on this work. It follows, by almost two hundred years, the English translation of his famous mathematics textbooks. However, intuition suggests that only one such final equation exists, which must be completely insensitive to the way it was obtained. Bézout was writing in the days before subscripting was in general use. Here, Bezout presents his approach to solving systems of polynomial equations in several variables and in great detail. His main research interest is the history of mathematics. The modest growth of algebraic analysis may not be attributed to this reason alone.

Unlike Euler, Bézout spent a considerable portion of his life engaged in teaching duties. The multiple and urgent tasks imposed upon you today do not, nevertheless, deviate your sight from the future. And those methods essentially all reduce to recasting the system under study to equations involving only one unknown. Resulting simplifications in the polynomial multipliers 196 More applications, etc. It follows, by almost two hundred years, the English translation of his famous mathematics textbooks. We did not even know how many useless coefficients there were. Euler gave means to reach the final equation devoid of any superfluous factor and at the same time determined the actual degree of the final equation, in the special case when these equations are complete or when the missing terms are those in the highest powers of one or the other unknown.

Here, Bézout presents his approach to solving systems of polynomial equations in several variables and in great detail. Its goal is to push and improve a sub-part of the mathematical sciences, to be used by all other sciences for their own advancement. Whether the extent of these difficulties was perceived or not, they could already be felt in the case of equations involving two unknowns. First of all, he published a six-volume elementary mathematics text, based on the classes he taught to naval and artillery cadets. It is clear that if we use these equations for arbitrary purposes, then the number of useful coefficients is not the the total number of terms in the polynomial, but rather the difference between the number of terms and the number of terms constrained by the arbitrary equations. Our previous observation showed that the final equation obtained through this process can vary, depending upon the order in which the process is applied.

However, although the results of these combinations have no superfluous factor, they remain more complicated than necessary. Determination of the degree of the final equation in all cases 320 Remark 327 Follow-up on the same subject 328 About equations whose number is smaller than the number of unknowns they contain. His interests span numerical analysis, optimization, systems analysis, and their applications to aerospace engineering. About equations where the number of unknowns is lower by one unit than the number of these equations. But what must these functions be to provide a satisfactory outcome? Once these fundamental ideas were established, I had to apply them. And where the unknowns, combined two-by-two, three-by-three, four-by-four etc. It is also deceptive regarding the true degree of the final equation.

By applying these means and these ideas to complete equations, we found the following general theorem: The degree of the final equation resulting from an arbitrary number of complete equations, containing an equal number of unknowns, and of arbitrary degrees, is equal to the product of the powers of the degrees of these equations. These questions are precisely the core difficulty of the problem. The strenuous process of translating 18th century French into English is not error-free. This book provides the first English translation of Bezout's masterpiece, the General Theory of Algebraic Equations. Research therefore started with low-degree equations in two unknowns. We already know the plot, but here we meet all the characters, major and minor. Therefore, since we can truly express all the original questions via this process, the terms that may still contain the unknowns to be eliminated must disappear by themselves.
