## Homework Statement

## Homework Equations

\int dx/(1-x^2)^3

## The Attempt at a Solution

I believe I have to use partial fractions to solve this integral. I started out by expanding the denominator

1/-(1 - 3x^2 + 3x^4 - x^6)

I pulled out a negative then separated by polynomial

x^4 (x^2 + 3) - 3(x^2 + 3) - 8

so:

-(x^4 - 3)(x^2 + 3) - 8

I'm lost..I need help
