simplify x+2/3x-6 * x^2-3x+2/x^2-x-6
and -7/2 + 3-x/x
I am sure you meant:
(x+2)/(3x-6) * (x^2 - 3x + 2)/(x^2 - x - 6)
= (x+2)/(3(x-2)) * (x-1)(x-2)/( (x-3)(x+2) )
= (x-1)/(3(x-3) ) , x ≠ ±2 , 3
and -7/2 + 3-x/x
(x+2)/(3x-6) * (x^2 - 3x + 2)/(x^2 - x - 6)
= (x+2)/(3(x-2)) * (x-1)(x-2)/( (x-3)(x+2) )
= (x-1)/(3(x-3) ) , x ≠ ±2 , 3
