: i think i fixed the parenthesis on these problems
: 1/(x-1)+ x/(x+2)=2
: 2/(x^2-1)+ 1/(x+1)=5
The lowest common denominator for the first one will be [(x-1)*(x+2)]
so multiply both sides of the equation by that & see if you can solve it.
Do you understand that? If you still have doubts, or if you get stuck, post again, but show us your attempt to solve it so we can see where the confusion is.
