If aB=c/a and a+B=-b/a.
First simplify them to the aB and a+B format
and then substitute the value.
My method was,
(a+B)(a^2+B^2-aB)
How should I simplify a^2+B^2?

When I simplified a%5E3%2Bb%5E3, I got %28a%2Bb%29%28a%5E2-ab%2Bb%5E2%29
I do not know how to simplify in terms of ab. I have never heard of that. Do you have a certain textbook page or website you can show me, because I have no idea what that is.
