You can put this solution on YOUR website!
(2n)/(1-n) + (n+3)/(n2-1)
2n/ -1(n-1) +(n+3)/ (n+1)(n-1)
-2n/ (n-1) + n+3 / (n+1)(n-1)
(n+1)(n-1) is the LCM
-2n(n+1) +(n+3) / (n+1)(n-1)
-2n^2-2n +n+3 / (n+1)(n-1)
-2n^2-n+3 / (n+1)(n-1)
-1(2n^2+n-3)/ (n+1)(n-1)
-1(2n^2+3n-2n-3)/(n+1)(n-1)
-1{n(2n+3)-1(2n+3)}/(n+1)(n-1)
-1(n-1)(2n+3) / (n+1)(n-1)
-(2n+3)/n+1)
