$\left(\sqrt{10 x^4}-x \sqrt{5 x^2}\right)\left(2 \sqrt{15 x^4}+\sqrt{3 x^3}\right)$
A$10 x^4 \sqrt{6}+x^3 \sqrt{30 x}-10 x^4 \sqrt{3}+x^2 \sqrt{15 x}$
B$10 x^4 \sqrt{6}+x^3 \sqrt{30 x}-x^4 \sqrt{75}+x^2 \sqrt{15}$
C$10 x^4 \sqrt{6}+x^3 \sqrt{30 x}-10 x^4 \sqrt{3}-x^2 \sqrt{15}$
D$10 x^4 \sqrt{6}+x^3 \sqrt{30 x}-10 x^4 \sqrt{3}-x^3 \sqrt{15 x}$
$\left(\sqrt{10 x^4}-x \sqrt{5 x^2}\right)\left(2 \sqrt{15 x^4}+\sqrt{3 x^3}\right)$
A$10 x^4 \sqrt{6}+x^3 \sqrt{30 x}-10 x^4 \sqrt{3}+x^2 \sqrt{15 x}$
B$10 x^4 \sqrt{6}+x^3 \sqrt{30 x}-x^4 \sqrt{75}+x^2 \sqrt{15}$
C$10 x^4 \sqrt{6}+x^3 \sqrt{30 x}-10 x^4 \sqrt{3}-x^2 \sqrt{15}$
