СРОЧНО!!! ДАЮ 50 БАЛЛОВ!!!

Answer 1

$\frac{\sqrt{6} -\sqrt{2} }{\sqrt{6} +\sqrt{2} } -\frac{\sqrt{6} +\sqrt{2} }{\sqrt{6} -\sqrt{2} }$

$\frac{(\sqrt{6} -\sqrt{2} )(\sqrt{6} -\sqrt{2} )-(\sqrt{6} +\sqrt{2} )(\sqrt{6} +\sqrt{2} )}{(\sqrt{6} +\sqrt{2} )(\sqrt{6} -\sqrt{2} )}$

$\frac{6-2\sqrt{12} +2-6-2\sqrt{12} -2}{6-2}$

$\frac{-4\sqrt{12} }{4} =-\sqrt{12} =-2\sqrt{3} \\(-2\sqrt{3} )^2=4*3=12$
