# Thread: The original EQ, from this first derivative

1. ## The original EQ, from this first derivative

f '(x) = x^2(x+1)^3

Thanks for the help

What you want to find is $\int x^2 (x+1)^3 ~ dx$.
The most straightforward way to do this is $x^2(x+1)^3 = x^5 + 3x^4+3x^3+x^2$. And do the integral from there.

3. Thanks, that made it alot easier!
