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

We take the first number in the first section, and multiply that against each number in the second section.

2x*2y = 4xy

2x*8=16x

So the beginning part of our equation is 4xy + 16x. Now we need to do the second number in the first section the same way. Remember to bring the subtraction sign!!

-2y*2y = -4y^2

-2y*8 = -16y

We add this to the first result:

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

hope it helps!!

Step-by-step explanation:

My method is to "square them"

2x.          -2y.      

                         2y

                         8

2x * 2y

2x * 8

-2y*2y

-2y * 8

and add all the products together
