Factoring a polynomial means expressing it as a product of other polynomials.
GCF Method • Factoring polynomials with a common monomialfactor (using GCF). **Always look for a GCF before using any other factoring method.
Difference of Squares Method • A Difference of Squares is a binomial (2 terms only) and it factors like this: *USE YOUR PERFECT SQUARES!! **REMEMBER TO CHECK FOR A GCF FIRST!!!
Factoring Trinomials in the form 1. Write two sets of parenthesis, ( )( ). These will be the factors of the trinomial. 2. Think of factors of c that add up to b.
Example 7 Which binomial is a factor of ? • (x + 2) • (x + 8) • (x – 1) • (x + 4)
Example 8 Which binomial is a factor of ? • (x - 3) • (x + 4) • (x – 12) • (x - 2)
Factoring Trinomials in the form • Trial and Error • Write two sets of parenthesis ( )( ) • Find two factors of a. • Find two factors of c. • Check to see if the factors will add up to b.
