... or any nonzero multiple thereof (for example, you could multiply everything by three and it would still be correct, of course). One cannot divide by a, because a might equal zero. Another common error was to forget that N (A) is here a subspace of R3 : it is the solution space to a matrix equation w ...

... Factoring a polynomial can make a problem easier to solve or allow one to easily find the roots of an equation. Factoring can be thought of as the opposite of distribution because terms are expanded, usually from a trinomial (three term) equation to an equation which is the product of two binomial ( ...

System of polynomial equations

A system of polynomial equations is a set of simultaneous equations f1 = 0, ..., fh = 0 where the fi are polynomials in several variables, say x1, ..., xn, over some field k.Usually, the field k is either the field of rational numbers or a finite field, although most of the theory applies to any field.A solution is a set of the values for the xi which make all of the equations true and which belong to some algebraically closed field extension K of k. When k is the field of rational numbers, K is the field of complex numbers.
