Answer 2

$\huge{ \bf{ \underline{ \underline{question}}}}$

$(3a + 2b)(a - 5b)(2a + b)$

$\huge{ \bf{ \underline{ \underline{expand}}}} \: \\ \implies \: 6 {a}^{3} - 23 {a}^{2} b \: - 33a {b}^{2} - 10 {b}^{2}$

$\huge{ \bf{ \underline{ \underbrace{explanation}}}} \\ \implies \: (3a + 2b)(a - 5b)(2a + b)$

Apply the distributive law;

$(a +b)(x + y + z) \\ = ax + ay + az + bx + by + bz$

$(3 {a}^{2} - 13ab - 10 {b}^{2} )(2a + b) \\ \implies \: 3 {a}^{2} (2a + 3 {a}^{2} - 13ab) \\ \implies \: (2a - 13abb - 10 {b}^{2} ) \\ \implies \: (2a - 10 {b}^{2} b)$

Simplify;

$3 {a}^{2} (2a + 3a {}^{2} b - 13ab) \\ \implies \: 6 {a}^{3} - 23 {a}^{2} b - 33a {b}^{2} - 10 {b}^{3}$

$\huge{ \bf{ \green{ \underline{ \underbrace{hence \: verified}}}}}$

$6 {a}^{3} - 23 {a}^{2} b - 33 {ab}^{2} - 10 {b}^{3}$
