[latex] \frac{ \sqrt{12}- \sqrt{8} }{ \sqrt{2}- \sqrt{3} } [/latex]+[latex] \frac{(1- \sqrt{2})^2 -(2- \sqrt{2} )^2 }{2 \sqrt{2}-3 } [/latex] упростите выражение, очень срочно

[latex] \frac{\sqrt{12}-\sqrt8}{\sqrt2-\sqrt3} + \frac{(1-\sqrt2)^2-(2-\sqrt2)^2}{2\sqrt2-3} = \frac{2\sqrt3-2\sqrt2}{\sqrt2-\sqrt3}+ \frac{(1-\sqrt2-2+\sqrt2)(1-\sqrt2+2-\sqrt2)}{2\sqrt2-3} =\\\\= \frac{-2(\sqrt2-\sqrt3)}{\sqrt2-\sqrt3} +\frac{-1\cdot (3-2\sqrt2)}{-(3-2\sqrt2)} =-2+1=-1[/latex]
