Answer:

b

Step-by-step explanation:

(a - b)² = a² - 2ab + b²

(2x - 6)² = (2x)² - 2*2x *6 + 6²

             = 4x² - 24x + 36

Answer: b

Step-by-step explanation:

(2x-6)^2

(2x-6)(2x-6)

(2 X times 2x = 4x^2

(2x times -6 = -12x

-6 times 2x= -12x

-6times -6 = 36

So you get 4x^2-12x-12x+36

Combine the x's. You get 4x^2 -24x+36
