Distribute and simplify the radicals below (√12+6)(-√8-√2)

Hatshy [7]

For this case we have the following expression:

$(\sqrt {12} +6) (- \sqrt {8} - \sqrt {2})$

We apply distributive property:

$(\sqrt {12} * - \sqrt {8}) + (\sqrt {12} * - \sqrt {2}) + (6 * - \sqrt {8}) + (6 * - \sqrt {2} ) =\\- \sqrt {96} - \sqrt {24} -6 \sqrt {8} -6 \sqrt {2} =$

We rewrite in equivalent form:

$- \sqrt {4 ^ 2 * 6} - \sqrt {2 ^ 2 * 6} -6 \sqrt {2 ^ 2 * 2} -6 \sqrt {2} =\\-4 \sqrt {6} -2 \sqrt {6} -6 * 2 \sqrt {2} -6 \sqrt {2} =$

$-4 \sqrt {6} -2 \sqrt {6} -12 \sqrt {2} -6 \sqrt {2} =\\-6 \sqrt {6} -18 \sqrt {2}$

Answer:

$-6 \sqrt {6} -18 \sqrt {2}$
