Answer 2

$\sf{\displaystyle 2a\left(3a^2-6b\right)-\frac{1}{2}b\left(2ab+8a\right)}$

$\sf{\displaystyle =2a\left(3a^2-6b\right)-\frac{b\left(2ab+8a\right)}{2}}$

$\sf{=2a\left(3a^2-6b\right)-ab\left(b+4\right)}$

$\sf{=6a^3-12ab-ab\left(b+4\right)}$

$\sf{=6a^3-12ab-ab^2-4ab}$

$\sf{=6a^3-ab^2-12ab-4ab}$

$\sf{=6a^3-ab^2-16ab}$
