1. change (x^2 - y^2)^3 to (x-y)^3 x (x+y)^3 you should write the devision as fraction so it can be easier for you to simplify 2. then you simplify (x+y) and (x+y)^3 => x^3-y^2 over (x-y)^3 x (x+y)^2 and there you go! i hope it helped and you can give me brainliest if you want to, that would mean a lot
