Factoring GCF’s, differences of squares, perfect squares, and cubes
Objectives You will be able to factor: Greatest common factors Differences of squares Perfect squares Sums and differences of cubes
Greatest common factor (GCF) Definition: Coefficient and variables that are common to all terms in a polynomial Ex 1: GCF: Factored Form: Ex 2: GCF: Factored Form: Ex 3: GCF: Factored Form:
Practice 1. 2. 3. 4. 5. 6.
Differences of Squares Formula: Ex 1: Ex 2: Ex 3: Ex 4: PRIME! It’s not a difference! Ex 5:
Sums and Differences of Cubes Formula: Ex 1: a=x b=2 Try 2: Ex 3: Try 4:
Perfect square trinomials Formula: Figure it out How do we go from here to here?
Perfect square trinomials Formula: Ex 1: Ex 2: Ex 3: Ex 4: Ex 5:
Factoring Completely Always look for a GCF first Check the result to see if it can be factored further 1. 2. 3. 4. 5.
