Question

(x^2 - y^2)/(3x - 3y) = ?

Answer 1

`(x+y)/(3)`

Explanation:

`(x^(2)-y^(2) )/(3x-3y)`

use the difference of two squares formula

`((x+y)(x-y))/(3y-3) \\\\factor out 3 ((x+y)(x-y))/(3(x-y)) \\cancel out the common factor; (x-y)\\your answer is`

x+y/3

Answer 2

I don’t really know but I think you can get like (x-y)(x+y) = 3(x-y). And then you like do 3(x+y)(x-y)??
