Yes, there is a discontinuity at x=2, but it isn't removable. The two x-1 terms cancel (and are thus removed). You can remove one of the x-2 terms in the denominator but not the other, so the discontinuity remains.
As Philip noted, a discontinuity in a function is only removable if the term in the function that caused the discontinuity can be canceled. Another way to look at it is that a vertical asymptote, such as the one at x=2 in this case, is a discontinuity that cannot be removed.
