  1. Ch6 (6-1 & 6-2) Portfolio Page -- Algebra 2 Ex1: If x – 3 is a factor of the polynomial, then 3 is the zero. Ex2: If 3 is a zero of the polynomial, then x – 3 is a factor. Factor Theorem The expression (x – a) is a linear factor of a polynomial if and only if the value ais a zero of the related polynomial function
