Section 10.8 Factoring Using a GCFSWBAT to factor a polynomials using a GCF

What does it mean to factor?

•Factoring a polynomial means to rewrite the polynomial as a product

•Ex: The factored form of 6 is 2∙3

Factoring Using a GCF

•One way (and yes, you will learn the other ways) to factor a polynomial is by using the GCF

Factoring Using a GCF

•Step 1: Identify the GCF of the terms•Step 2: Divide the GCF from the rest of

the terms•Step 3: Rewrite as a product (Use

parenthesis)
