Homework Statement



(3x^2-4)/(x^3-4x-6)

Homework Equations



I guess integration by parts... But how do i set this up?

The Attempt at a Solution



The numerator is exponentially lower than the denominator, so no long division.
The denominator seems not to factor out into anything... I tried doing a perfect squares situation, by factoring x out of the first two terms, but to no avail... Am I doing something wrong?

Try a u substitution u=x^3-4*x-6. Numerator look familiar?

Wow, I'm an idiot... hahaha... Too busy trying my new integration skills and forgot substitution.
 
Substitution is one of the first techniques you learn, and is one of the simplest to use. So that should be one that you think about using first. Even if it's not applicable, you haven't wasted that much time.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
