They show how to do this kind of equation here. First you factor x^2 - x and x^2 + x to be x(x - 1) and x(x + 1). Then you factor the difference of squares to get x^2 - 1 to be (x - 1)(x + 1). Then multiply through by the common denom x(x - 1)(x + 1). Then solve the quadratic.This is actually in the Linear Equations section of my book. I've looked everywhere for a similar problem. please help me break it down.
x/(x^2-1) - (x+3)/(x^2-x) = -3/(x^2+x)
