Answer:
=4xy−4y2+16x−16y
Step-by-step explanation:
(2x−2y)(2y+8)
=(2x+−2y)(2y+8)
=(2x)(2y)+(2x)(8)+(−2y)(2y)+(−2y)(8)
=4xy+16x−4y2−16y
=4xy−4y2+16x−16y
Answer:-4y^2+4xy+16x-16y
Step-by-step explanation: Hi there.
For this answer I will show you the FOIL method.
Form: (ax-by)(cy-d)
1. Multiply ax and cy
2x*2y=4xy
2. Multiply ax and d
2x*8=16x
3. Multiply by and cy
-2y*2y=-4y^2
4. Multiply by and d
-2y*8=-16y
Add all of them together and you get:
-4y^2+4xy+16x-16y
Have a nice day! :)
