SOLUTION: Good evening.
My question:
Multiply (x^r-y^f)(x^2r + y^2r)
(x^r * x^2r) (-y^f * y^2r)
(x^4r2) (-y^f2r)
x^3r-y^3f x^3r-y^3f
I don't know if I'm on the right track

Thank you! Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Multiply (x^r-y^f)(x^2r + y^2r)
------------------------
= x^r(x^(2f) + y^2r) - y^f(x^(2f) + y^2r)
---
= x^(r+2f) + y^(2r)*x^r - y^f*x^(2f) - y^(f+2r)
