... 8-5 The Remainder and the Factor Theorems Remainder Theorem: If P(x) is a polynomial of degree n (n>0), then for any number r, P(x)= Q(x) (x-r)+P(r) , where Q(x), is a polynomial of degree n-1. For the polynomial P(x), the function value P(r) is the remainder when P(x) is divided by x-r. Factor Theo ...

... is a polynomial with positive degree, i.e. n > 1 and an 6= 0 such that T (W ) is a zero function. It follows from the Bezout’s theorem that W has at most n roots (in fact this is true over any integral domain). Thus since k is an infinite field, then there exists a ∈ k which is not a root of W . In ...
