#=> -32sqrt(3x)#

Explanation:

#4\sqrt { 12x } + 5\sqrt { 48x } - 10\sqrt { 108x }#

#=> 4\sqrt { 4xx3x } + 5\sqrt { 16xx3x } - 10\sqrt { 36xx3x }#

#=> 4xx2\sqrt { 3x } + 5xx4\sqrt { 3x } - 10xx6\sqrt { 3x }#

#=> 8\sqrt {3x } + 20\sqrt { 3x } - 60\sqrt {3x }#

#=> sqrt(3x)(8+20-60)#

#=> sqrt(3x)(-32)#

#=> -32sqrt(3x)#
