Answer 1

6a^3-12ab-ab^2-4ab =6a^3-16ab-ab^2

Answer 2

$2 {a}(3 {a}^{2} - 6b) - \frac{1}{2} b(2ab + 8a) \\ \\ multiply \: 2a \: with \: bracket \\ \\ 2a \times 3 {a}^{2} - 2a \times 6b - \frac{1}{2} b(2ab + 8a) \\ \\ 6 {a}^{3} - 12ab - \frac{1}{2} b(2ab + 8a) \\ \\ factor \: out \: 2 \: from \: (2ab + 8a) \\ \\ {6a}^{3} - 12ab - \frac{1}{2} b \times 2(ab + 4a)$


$reduce \: the \: fraction \\ \\ {6a}^{3} - 12ab - b(ab + 4a) \\ \\ mutliply \: - b \: with \: (ab + 4a) \\ \\ {6a}^{3} - 12ab - {ab}^{2} - 4ab \\ \\ collect \: like \: terms \\ \\ {6a}^{3} - 16ab - {ab}^{2}$
