**[SOLVED] Partial Fractions**

**1. Evaluate:**

[tex]\int \frac{dx}{x^{2} -1}[/tex]

[tex]\int \frac{dx}{x^{2} -1}[/tex]

Attempt:

[tex]\int \frac{dx}{x^{2} -1}[/tex]

[tex]= \int \frac{dx}{(x+1)(x-1)}[/tex]

[tex]= \frac{A}{(x+1)} + \frac{B}{(x-1)}[/tex]

[tex]= \frac{Ax - A + Bx + B}{(x+1)(x-1)}[/tex]

Where do I got from here? Thanks
