BTW Shahfahad, could you be strict with your formatting in your future algebra posts? I'm able to follow what you mean to type, but there are some difficult ambiguities in some of your expressions that force us to spend a lot of time correcting and assuming. (For instance, (x + 1 / x - 1)² should be ((x+1)/(x-1))².)
