Notes: Section P.4 Factoring Polynomials What does it mean to factor a number? What about a polynomial expression? Common Factors The first step any time we factor is to check for a Greatest Common Factor (GCF) and factor it out. What is a GCF?Example 1: Find the GCF of each: a.12 & 60b. & 6x520x2Example 2: Factor using the GCF: a.x5x53− 12b.
