You can put this solution on YOUR website!
you can't solve this, it is not an equation, (no equal sign), but you can simplify
:
2%2F%28%285x-45%29%29+%2B+x%2F%28%28x%5E2-81%29%29
:
Factor, (x^2-81 is the difference of squares):
2%2F%285%28x-9%29%29+%2B+x%2F%28%28x-9%29%28x%2B9%29%29%29
:
Mult each term by the common denominator 5(x-9)(x+9), resulting in:
%282%28x%2B9%29+%2B+5x%29%2F%285%28x%2B9%29%28x-9%29%29
:
%282x%2B18+%2B+5x%29%2F%285%28x%2B9%29%28x-9%29%29
:
%287x%2B18%29%2F%285%28x%2B9%29%28x-9%29%29; about all you can do with it
