3-102.

Calculate each of the following products by drawing and labeling an area model or by using the Distributive Property. Homework Help ✎

1. $- 4 y ( 5 x + 8 y )$

• Review the Math Notes box in this lesson.

$−20xy + −32y^2$

1. $9 x ( - 4 + 10 y )$

• See part (a).

1. $( x ^ { 2 } - 2 ) ( x ^ { 2 } + 3 x + 5 )$

• Use an area model or the Distributive Property. Review the Math Notes box in this lesson.

The first term in the binomial is $x^2$, It should be multiplied (distributed) into the trinomial.
