(2x-2y)(2y+8)
= (2x)*(2y)+(2x)*8-(2y)(2y)-(2y)*8
= 4xy+ 16x- 4y^2- 16y

The correct answer is D. 4xy+ 16x- 4y^2- 16y~

Answer:

The answer is the option D


4xy+16x-4y^(2)-16y

Explanation:

we have


(2x-2y)(2y+8)

Multiply applying the distributive property


(2x-2y)(2y+8)=2x*2y+2x*8-2y*2y-2y*8


=4xy+16x-4y^(2)-16y
