Hi
Solving for x
{{{1/(x-1) + 1/(x+2) =3/(x^2+x-2)}}}     |Multiplying thru with (x-1)(x+2)
    (x+2) + (x-1)  = 3
    x^2 + x - 2 = 0   |combining Like terms
factoring
 (x+2)(x-1)= 0 Note:SUM of the inner product(2x) and the outer product(-x) = x 
 (x+2)= 0    x = -2 Extraneous - cannot divide by zero
 (x-1)= 0    x = 1  Extraneous - cannot divide by zero
 NO solution
