Question

What is the following product?
(Square root 12 + square root 6) (square root 6 - square root 10)

Answer 1

Answer:

$6\sqrt{2}-2\sqrt{30}+6-2\sqrt{15}$

Step-by-step explanation:

$(\sqrt{12} +\sqrt{6} )(\sqrt{6}-\sqrt{10} )$

$\ \sqrt{12} \sqrt{6} -\sqrt{12} \sqrt{10} +\sqrt{6} \sqrt{6} -\sqrt{6} \sqrt{10}$

$\sqrt{72} -\sqrt{120} +\sqrt{36} -\sqrt{60}$

$6\sqrt{2}-2\sqrt{30}+6-2\sqrt{15}$
