See below.

Explanation:

Not sure if this is:

#3(sqrt(x-6))^2color(white)(8888)# or #color(white)(8888)3(2sqrt(x)-6)^2#

For: #3(sqrt(x-6))^2#

#3(sqrt(x-6))^2=3(sqrt(x-6)*sqrt(x-6))#

#color(white)(888888888.)=3(x-6)#

#color(white)(888888888.)=3x-18#

For:

#3(2sqrt(x)-6)^2#

#3(2sqrt(x)-6*2sqrt(x)-6)#

#=3(2sqrt(x)*2sqrt(x)-6*2sqrt(x)-6*2sqrt(x)-6*-6)#

#=3(4x-24sqrt(x)+36)#

#=12x-72sqrt(x)+108#
