#24/((x-6)(x-2))#

Explanation:

The denominators need to be the same to combine the fractions so times #(x+2)# to the Left fraction and #(x-6)# to the right one.

#3/(x-6)*(x+2)/(x+2)-3/(x+2)*(x-6)/(x-6)#

#(3(x+2))/((x-6)(x-2))-(3(x-6))/((x+2)(x-6))#

#(3(x+2)-3(x-6))/((x-6)(x-2))#

#(3x+6-3x+18)/((x-6)(x-2))#

#24/((x-6)(x-2))#
