This chapter discusses symmetric functions of the roots of a polynomial equation. Formulae involving only a limited number of algebraic operations have been worked out for the general cubic and quartic equations, but N. H. Abel proved that the general equations of fifth and higher degrees cannot...

Polynomial equations are solved by setting the function equal to 0. Then the values of x that make this true are calculated by guessing, factoring. using the quadratic formula, or rational zeroes theorem. What is an example of a polynomial equation? Some examples of polynomial equations are 3x...
The product of the roots is (5 + √2) (5 − √2) = 25 − 2 = 23 And we want an equation like: ax2 + bx + c = 0 When a=1 we can work out that: Sum of the roots = −b/a = -b Product of the roots = c/a = c Which gives us this result x2 − (sum of...
PROSPECTS FOR A CENTRAL THEORY OF PARTIALDIFFERENTIAL EQUATIONSJ. W. NEUBERGER1. IntroductionThree episodes in the history of equation solving are: Finding roots of poly-nomials, solution of ordinary differential equations, solution of partial differentialequations. The first two episodes went through ...
