Question

(\sqrt{3}-\sqrt{2})^{2}-2(1-\sqrt{6})-(\sqrt{3}-\sqrt{2})(\sqrt{3}+\sqrt{2})obtem-se

Answer 1

$(\sqrt{3} - \sqrt{2})^2 - 2(1 - \sqrt{6}) - (\sqrt{3} - \sqrt{2})(\sqrt{3} + \sqrt{2}) = \\\\ (3 - 2\sqrt{6} + 2) - 2 + 2\sqrt{6} - (3 - 2) = \\\\ 5 - 2\sqrt{6} - 2 + 2\sqrt{6} - 1 = \\\\ 5 - 3 \\ \boxed{2}$
