Question

Hich products result in a difference of squares? Select three options.

(x minus y)(y minus x)
(6 minus y)(6 minus y)
(3 + x z)(negative 3 + x z)
(y squared minus x y)(y squared + x y)
(64 y squared + x squared)(negative x squared + 64 y squared)

Answer 1

C,B,D

Explanation:

Answer 2

Answer: (3+xz)(-3+xz); (y^2-xy)(y^2+xy) ; (64y^2+x^2)(-x^2+64y^2)

Explanation:

The formula for difference of squares is (a+b)(a-b)= a^2-b^2.

The first 2 don't work.

The 3rd one can be written as (3+xz)(3-xz).

The 4th and 5th can be written the same way.
