Hi guys, i'm new here, just registered, so I want to greet you all first.

Could you please help me with solving this expression, the result should be 0, but I can't seem to get read of all the factors..

Here it is: 1/x+1 - 2/(x+1)^2 - x^2-1/(x+1)^3

Could you please mention how are you doing the factoring?

Thanks million.
