... 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 .
