(adsbygoogle = window.adsbygoogle || []).push({}); Integral of 2/(x^2-1)dx HELP!!!

1. The problem statement, all variables and given/known data

Evaluate: ∫2/(x^{2}-1)dx

2. Relevant equations

Inverse trig functions arent working.

∫1/x+1dx=ln(1+x)

3. The attempt at a solution

My tutor and i both attemped the solution many ways, and are still at a stand still.

According to my calculator and wolfram alpha, the answer is -ln(x+1/x-1)

The closest i have gotten is 2∫[itex]1/((x+1)(x-1))[/itex]dx
