<font face="Garamond" size="+2">

FOIL it.


First:  *[tex \LARGE 4\sqrt{3}\,\cdot\,3\sqrt{6}\ =\ 12\sqrt{18}\ =\ 12\sqrt{9\,\cdot\,2}\ =\ 36\sqrt{2}]


Outside:  *[tex \LARGE 4\sqrt{3}\,\cdot\,4\ =\ 16\sqrt{3}]


Inside: *[tex \LARGE -1\,\cdot\,3\sqrt{6}\ =\ -3\sqrt{6}]


Last: *[tex \LARGE -1\,\cdot\,4\ =\ -4]


String 'em together:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 36\sqrt{2}\ +\ 16\sqrt{3}\ -\ 3\sqrt{6}\ -\ 4]
