1. WARM UP FACTOR

3. Factoring a polynomial means expressing it as a product of other polynomials.

4. Factoring polynomials that are a Sum and Difference of cubes. Factoring Method #4

5. THIS IS NEW YOU DID NOT GO OVER THIS IN ALGEBRA 1 SO MAKE SURE TO PAY ATTENTION AND ASK QUESTIONS!

6. Sum and Difference of Cubes:

7. ASK YOURSELF WHAT IS A? WHAT IS B? THEN PLUG A AND B INTO THE FORMULA

8. Rewrite as cubes Write each monomial as a cube and apply either of the rules. Apply the rule for sum of cubes:

9. Rewrite as cubes Apply the rule for difference of cubes:

10. Factoring Method #5 Factoring By Grouping for polynomials with 4 or more terms

11. FACTORING BY GROUPING 1. Group the first set of terms and last set of terms with parentheses. 2. Factor out the GCF from each group so that both sets of parentheses contain the same factors. 3. Factor out the GCF again (the GCF is the factor from step 2).

12. STEP 1: GROUP Example 1: Step 2: Factor out GCF from each group Step 3: Factor out GCF again

13. Example 2:
