1. 8-3 Multiplying Polynomials again
Goal:
Multiply polynomials using the FOIL method
Eligible Content: A

2. Vocabulary
FOIL Method – a method that can be used to multiply 2 binomials together.
If you like the Box Method, you can still use it.

3. FOIL F – first term in each parentheses O – outside terms
I – inside terms
L – last term in each parentheses

4. Multiply using the FOIL method
