%28%28b%29%2F%28b-1%29%29%2F%28b%5E2-1%29 Start with the given expression.


%28%28b%29%2F%28b-1%29%29%2F%28%28b%5E2-1%29%2F1%29 Rewrite b%5E2-1 as %28b%5E2-1%29%2F1



%28%28b%29%2F%28b-1%29%29%2A%281%2F%28b%5E2-1%29%29 Multiply the first fraction by the reciprocal of the second fraction.



%28%28b%29%2F%28b-1%29%29%2A%281%2F%28%28b%2B1%29%28b-1%29%29%29 Factor b%5E2-1 to get %28b%2B1%29%28b-1%29


%28b%29%2F%28%28b%2B1%29%28b-1%29%5E2%29 Combine and multiply the fractions


So %28%28b%29%2F%28b-1%29%29%2F%28b%5E2-1%29 simplifies to %28b%29%2F%28%28b%2B1%29%28b-1%29%5E2%29
