You can put this solution on YOUR website!
Do the numerator 1st:
------------
2%28x-1%29%2F%28%28x%2B1%29%2A%28x-1%29%29+%2B+1%2F%282%28x%2B1%29%29
= 2%2F%28x%2B1%29+%2B+1%2F%282%28x%2B1%29%29
= 4%2F%282%28x%2B1%29%29+%2B+1%2F%282%28x%2B1%29%29
= 5%2F2%28x%2B1%29
-----------------
Then the denominator:
%281%2F%28x%2B1%29%29+-+1+=+%281+-+%28x%2B1%29%29%2F%28x%2B1%29
= -x%2F%28x%2B1%29
-------------
Cancel the (x+1) in both.
= %285%2F2%29%2F%28-x%2F1%29
Invert the den and multiply
= %285%2F2%29%2A%28-1%2Fx%29+=+-5%2F2x
-5/2x
