Exercise 3 Page 446

Begin with the Distributive Property.

B

Practice makes perfect

To simplify the given expression, we will use the Distributive Property.

3a (2a+1 ) -(2a-2)(a+3)

Distribute 3a

6a^2+3a -(2a-2)(a+3)

Distribute (2a-2)

6a^2+3a -(2a-2)a-(2a-2)3

Distribute a

6a^2+3a -2a^2+2a-(2a-2)3

Distribute 3

6a^2+3a -2a^2+2a-6a+6

Add and subtract terms

4a^2-a+6

This corresponds to answer B.
