expand

(2 a - b) (4 a^{2} + 2 ab + b^{2})

8 a^{3} - b^{3}

Solution steps

(2 a - b) (4 a^{2} + 2 ab + b^{2})

Distribute parentheses

= 2 a \cdot 4 a^{2} + 2 a \cdot 2 ab + 2 a b^{2} - b \cdot 4 a^{2} - b \cdot 2 ab - b b^{2}

Simplify

2 a \cdot 4 a^{2} + 2 a \cdot 2 ab + 2 a b^{2} - b \cdot 4 a^{2} - b \cdot 2 ab - b b^{2} : 8 a^{3} - b^{3}

= 8 a^{3} - b^{3}
