Hi

Solving for x

     |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
