#-6sqrt3-9sqrt2#

First, distribute the #-3sqrt3# to both terms inside parentheses.

#-3sqrt3*2-3sqrt3*sqrt6#

Now simplify.

#-6sqrt3-3sqrt18#

18 is #2 times 3 times 3#.

#-6sqrt3-3sqrt(2times3times3)#

You have two factors of 3 inside the radical, so you can pull them out and make one factor of 3 outside the radical.

#-6sqrt3-3sqrt(2timescolor(limegreen)3timescolor(limegreen)3#

#-6sqrt3-3*color(limegreen)3sqrt2#

Finally, simplify again.

#-6sqrt3-9sqrt2#
