Ответ: $4\sqrt{6} +6\sqrt{2}-3\sqrt{3} -6$

Пошаговое объяснение:

$(2\sqrt{6} +1)(2+\sqrt{3} )-(\sqrt{6} +\sqrt{2})^2$ $1)(2\sqrt{6} +1)(2+\sqrt{3} )=4\sqrt{6} +2+2\sqrt{3*3*2} +\sqrt{3}=4\sqrt{6} +6\sqrt{2}+\sqrt{3}+2 }$ $2)(\sqrt{6} +\sqrt{2})^2=6+2+2\sqrt{3*2*2} =8+4\sqrt{3}$ $3)4\sqrt{6} +6\sqrt{2}+\sqrt{3} }-8+2-4\sqrt{3} =4\sqrt{6} +6\sqrt{2}-3\sqrt{3} -6$
