Be careful X is not the same as x. They are distinct variables.
(x+2) /( x-2) = (-3/x)
Be careful with parentheses
(x+2)*x=-3*(x-2)
x^2+2x=-3x+6
x^2+5x-6=0
(x+6)*(x-1)=0
x=-6, x=1

(X+2 / x-2) = (-3/x) I know you cross multiply but I'm stuck on how to..
-------
x(x+2) = -3(x-2)
x^2 + 2x = -3x + 6
------
x^2 + 5x - 6 = 0
-----
Factor::
(x+6)(x-1) = 0
-----
x = -6 or x = 1
