  • 1. Distributive PropertyThe product of a and (b + c):a(b + c) = ab + ac(b + c)a = ba + ca The product of a and (b - c)a(b - c) = ab - ac(b - c)a = ba - ca1

2. Examples: 1.) 4(x + 2) = 4(x) + 4(2)4x + 82.) (x + 1)9 = 9(x) + 9(1) 9x + 93.) 4(x - 2) = 4(x) - 4(2)4x - 84.) (x - 4)6 = (x)6 - (4)66x - 242 3.
