What is the completely factored form of x2 - 16xy 64y2? xy (x - 16 64y) xy (x 16 64y) (x - 8y) (x - 8y) (x 8y) (x 8y)

The question is asking us to find the completely factored form of x^2 - 16 x y + 64 y^2. We can see that this is the example for the squared binomial. The formula is: a^2 - 2 a b + b^2 = (a - b) ^2. In this question: a = x and b = 8 y. Therefore, x^2 + 16 x y + 64 y^2 = (x - 8 y) ^2 = (x - 8 y 9 (x - 8 y). Answer: C) (x - 8 y) (x - 8 y)
