{(x^2-5x+6)(x^2-3x+2)}/x^3-3x^2+4 =
:
{(x-6)(x+1)(x-1)(x-2)}/(x+1)(x-2)^2 =
:
{(x-6)(x-1)} / (x-2)
:
There are two limits
:
*****************************************
limit as x--->2 from the right is -infinity
limit as x--->2 from the left is infinity
*****************************************
:
you can see this from the plot of {(x-6)(x-1)} / (x-2)
:
the curves are asymptotic to x = 2

cancel (x-2) from top and bottom and subsitute
