I agree with arildno. Be polite and show us what you have done yourself.
Now, to help you do it yourself, use "partial fractions". The denominator of your fraction, [itex]1- x^2[/itex] factors as (x- 1)(x+ 1). That means we can write
[tex]\frac{2- x}{1- x^2}= \frac{A}{x- 1}+ \frac{B}{x+ 1}[/tex]
for some numbers A and B. Can you find them?
Do you know how to integrate [itex]A/(x- 1)[/itex] and [itex]B/(x+ 1)[/itex]?
