5. Distributive Property
Distributive Property: a(b + c) = ab + ac
Try with numbers:
5(3 + 4) (4 + 8) (9 – 3)

7. Distributive Property
Try with variables:
6(x + 2) x(x + 6) x(2x + 3)

8. FOIL Method
FOIL is an acronym for remembering how to multiply using the distributive property with binomials. Take the expression (x + 5)(x + 3):
F – firsts
O – outers
I – inners
L - lasts

9. FOIL Method (cont.) Practice with FOIL Method:
(x + 2)(x + 8) (x + 5)(x + 8)
3. (x – 4)(x + 2) (x + 7)(x – 3)
