Split them up! Instead of thinking of he numbers as (2X^4 - X^5)/64, try thinking of them as (2X^4/64) + (-X^5)/64. It'll make your life SO much easier. Very Happy

And just use the regular rules of integrating from that point on. The trick is just knowing that you can split them up. Very Happy

Use the quotient rule.

(f'(x)g(x)-f(x)g'(x))/[g(x)]^2

That's for differentiating though. Wink

Factor out the 1/64 out of the integral (since it's a constant), THEN you may split them up. Just remember to multiply both split integrals by 1/64 AFTER you're done integrating.
