Question

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

​

Answer 1

Step-by-step explanation:

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

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

(16x - 8y)(16x - 8y) - 8x + 4y

16x(16x - 8y) -8y(16x - 8y) - 8x + 4y

196x^2 - 128xy -128xy + 64y^2 - 8x +4y

196x^2 - 256xy + 64y^2 - 8x + 4y

4x (49x - 64y) + 64y^2 +4y - 8x

4x (49x - 64y) + 4y(16y + 1) - 8x
