2.6 The Distributive Property

What operation happens here?

Distributive Property A number outside parenthesis must be multiplied by everything inside Ex.

Think of it like this… Ex. 3(x + 2) = ??? ** 3 is the candy. We must share the candy with everyone. That is, we must share 3 with x & 2.

Distributive Property Think of it like this… Ex. -10(x + 9) = ??? -10 (x + 9) Uh oh! Don’t lose the negative sign as you distribute the spotlighted number!! -10(x) + -10(9) -10x x - 90

Think of it like this… Ex. -5(x – 7) = ??? -5 (x – 7) Make sure you know where your negative signs are in this problem!!!!!

Think of it like this… Ex. 3(2 x +3y – 4) = ??? 3 (2x + 3y – 4)

Think of it like this… Ex. -5(2 x – y ) = ??? -5 (2x – y) Make sure you know where your negative signs are in this problem!!!!!

EXAMPLE 1 2(x + 5)

EXAMPLE 2 8(1 + 2x)

EXAMPLE 3 5(x + 3)

EXAMPLE 4 (2x + 6)3
