ANSWER

D. 22-8√5

EXPLANATION

We want to expand

[tex](2 \sqrt{5} - 4)(3 \sqrt{5} + 2)[/tex]

We use the distributive property to obtain,

[tex]2 \sqrt{5} (3 \sqrt{5} + 2) - 4(3 \sqrt{5} + 2)[/tex]

We expand to get,

[tex]6(5) + 4 \sqrt{5} - 12 \sqrt{5} - 8[/tex]

Simplify to get,

[tex]22 - 8 \sqrt{5} [/tex]

The correct answer is D.
