Exercise 26 Page 25

Apply the Distributive Property.

36a^3+71a^2-14a-49

Practice makes perfect

To simplify the expression by finding the product of the given binomial and trinomial, we will apply the Distributive Property.

(4a+7)( 9a^2+2a-7 )

Distribute ( 9a^2+2a-7 )

4a( 9a^2+2a-7 )+7( 9a^2+2a-7 )

Distribute 4a

36a^3+8a^2-28a+7( 9a^2+2a-7 )

Distribute 7

36a^3+8a^2-28a+63a^2+14a-49

Add terms

36a^3+71a^2-14a-49
