the problem is
7x^2y + 28xy^2 - 35y^3 / 10x^3y - 8x^2y^2 - 2xy^3
ok so the first thing i did was get the GCD of both which was:
7y(x^2 + 4xy - 5y^2) / 2xy(x^2 - 4xy - y^2) then i factored which was:
7y(x + 5y)(x - y) / here's where im stuck. I can't seem to factor x^2 - 4xy - y^2
i tried different numbers but i can't get the 2 numbers to equal -4xy & -y^2
how do i solve this?
once i get it i can just cancel out anything similar and get my final answer but im stuck back there.
any suggestions?
