WebROOTS AND SYMMETRIC POLYNOMIALS DAVID SMYTH 1. From finding roots to factoring. To see the connection between nding roots and factoring the polynomial, we begin with the following easy lemma. It says that nding a root of f(x) is the same as factoring f(x) into (x ) and a lower factor. Lemma 1.1 (Remainder Theorem).
