You are adding two polynomials. It should not take 10 minutes to do. Multiplying them would take a bit longer to do, but that is not what the problem asks for.

All you have to do when adding polynomials is "collect" the terms with the same exponent of x, and the constants (if any), and add up the different powers of x separately.

You'd get 15x^2 + 3x in this case. The +x^3 and -x^3 terms cancel.
