3.2 The Factor Theorem and The Remainder Theorem

by x c, the remainder is either 0 or has degree less than the degree of x c. Since x cis degree 1, the degree of the remainder must be 0, which means the remainder is a constant. Hence, in either case, p(x) = (x c)q(x)+r, where r, the remainder, is a real number, possibly 0. It follows
