Vertical asymptote at x=6, because that would be where the function is undefined due to x-6 being in the denominator as a factor. Division by zero is impossible.
A hole is at x=2, because the binomial factor, x-2 is a factor in both the numerator and the denominator, giving the expression (x-2)/(x-2), which is 1; yet this expression IS still part of the rational expression given, and with x-2 in the denominator, x cannot be +2, since this would create a division by 0 when x=2.
Please note here, the hole at x=2 is not appearing properly:
