Question

-4(x-2y)^2+8 (x-2y)​

Answer 1

Answer:

-4(x-3y)^2 +8(x-2y)

-4(x^2+9y^2-6xy)+8x-16y

-4x^2-36y^2+24xy+8x-16y

Answer 2

Answer:-12x + 8y^2 - 16y

-4(x-2y)^2 + 8(x-2y)

-4x - -8y^2 + 8x - 16y

-4x - 8x + 8y^2 - 16y

-12x + 8y^2 - 16y

if you see, there are three variables to simplify in this answer. x, y, y^2

and as y and y^2 are different variables, we will not add them.
