Answer:

See the entire simplification process below:

Explanation:

First, to simplify this expression we can rewrite the numerator as follows:

#(3x - 6)/(x - 2) -> ((3 xx x) - (3 xx 2))/(x - 2) -> (3(x - 2))/(x - 2)#

We can now cancel terms to simplify the expression:

#(3color(red)(cancel(color(black)((x - 2)))))/color(red)(cancel(color(black)((x - 2)))) -> 3#

We need to exclude values where the numerator is #0#:

#x - 2 = 0#

#x - 2 + color(red)(2) = 0 + color(red)(2)#

#x - 0 = 2#

#x = 2#

This expression simplifies to #3# except where #x = 2#.
