Factoring • GCF – Greatest Common Factor • Difference of 2 Squares • Factoring by Grouping • Factoring Trinomials
Greatest Common Factor or GCF • The GCF is the greatest factor that divides evenly into each term of an expression • May recognize GCF easily • If not; • Find prime factors of each term • Determine the GCF • Factor out GCF and combine remaining terms
GCF Examples • 4x3 + 12x2 • 5a2b3– 30a3b2
Factoring a Difference of Two Squares a2 – b2 = (a + b)(a - b) A pattern that makes it easy to factor First recognize perfect squares and substitute for a and b
Difference of Two Squares Examplesa2 – b2 = (a + b)(a – b) #1. 25 – x2 #2. 3p2– 27q2
