Simplify the following expression: \[(10+\sqrt{2})(12-\sqrt{6})\]
\[12\sqrt{2}-10\sqrt{6}-\sqrt{3}+120\]
\[6\sqrt{2}-5\sqrt{6}-\sqrt{3}+60\]
\[12\sqrt{2}-10\sqrt{6}-2\sqrt{3}+60\]
\[6\sqrt{2}-5\sqrt{6}-2\sqrt{3}+60\]
Simplify the following rational expression: \[\frac{x^2-4}{x^2-x-6}\]
x = All real numbers
x = All real numbers except for 3 → x ≠ 3
x = 3,-3
x = All real numbers except for -3 → x ≠ -3
