$a^{-1} = {1 \over a}$ with this fact we can rewrite your equation as:${3x^{2} + 5y^{2} \over x + y}$ can you go from here?

Give me one more step if you could, it's been a while since I've done this.

i actually can't think on how to simplify more than that.. sorry

Maybe that's the solution. Thank you!
