We can factor the denominator on the right side:

Multiply BOTH sides by x(x-2) to get:




Factoring the left side:

x = {-1, 0}
Testing for extraneous solutions we find that 0 must be thrown out leaving:
x = -1

Hi,
solving


Multiplying each term by x(x-2) so as all denominators = 1
x(3x+2) + (x-2) = -2
3x^2 + 2x + x - 2 = -2
3x^2 + 3x = 0
3x(x+1) = 0
3x = 0
x = 0 this solution tossed out as one cannot have zero in the deominator
(x+1) = 0
x = -1
