You can put this solution on YOUR website!
First
(x+1)/(1-x)+ (x^2/(x^2-1)
(1-x) can become (x-1) by multiplying the top and bottom by -1
-(x+1)/(x-1) +(x^2)/(x+1)(x-1)
common denominator ix (x+1)(x-1)
numerator is -(x+1)(x+1)+x^2=-x^2-2x-1+x^2=-2x-1
answer is (-2x-1)/(x^2-1) or A
==================
second is
1+(1/x) all over 1-(1/x)
multiply everything by x
x+1/x-1 or A
