You can put this solution on YOUR website!
I think you mean like this.
%28a-1%29%2F%28a%2B1%29%2B%28a%2B1%29%2F%28a-1%29
To add fractions, you need a common denominator.
The lowest common denominator would be (a+1)(a-1).
Multiply the first fraction by (a-1)/(a-1) and
the second fraction by (a+1)(a+1) to achieve that.
