pantera1 [17]

Answer:

-22

Step-by-step explanation:

We need to multiply the following:

$(\sqrt{10} +2\sqrt{8})(\sqrt{10}-2\sqrt{8})$

First, we need to FOIL out this expression, then we can simplify it

$(\sqrt{10} +2\sqrt{8})(\sqrt{10}-2\sqrt{8})\\\\(\sqrt{10})( \sqrt{10} )+(2\sqrt{8})(\sqrt{10})-(2\sqrt{8})( \sqrt{10})-(2\sqrt{8})(2\sqrt{8}) \\\\10+2\sqrt{80} -2\sqrt{80} -4\sqrt{64} \\\\10-4(8)\\\\10-32\\\\-22$
