Factoring by GroupingHandout

Steps:1. Make sure the

exponents are in descending order.

2. Group the first two terms and factor out GCF

3. Group next two terms and factor out GCF.

4. Rewrite as product of GCF’s and what was in the parenthesis (should be same expression in both parenthesis)

5. Factor anything that is left to factor.
