1. The problem statement, all variables and given/known data 3/x^2+2x - 2/x^2+x-2 + 4/x^2(x-1) Find the lowest common denominator and solve. 2. Relevant equations 3. The attempt at a solution I factored x(x+2) - (x-1)(x+2) + x^2(x-1) It looks like (x+2), (x-1) are common but what to do with the x & x^2 left over? Thank you in advance.
