expand (a-3b)(a^2+2ab-4b^2)

expand

(a - 3 b) (a^{2} + 2 ab - 4 b^{2})

a^{3} - a^{2} b - 10 a b^{2} + 12 b^{3}

Solution steps

(a - 3 b) (a^{2} + 2 ab - 4 b^{2})

Distribute parentheses

= a a^{2} + a \cdot 2 ab + a (- 4 b^{2}) - 3 b a^{2} - 3 b \cdot 2 ab - 3 b (- 4 b^{2})

Simplify

a a^{2} + a \cdot 2 ab + a (- 4 b^{2}) - 3 b a^{2} - 3 b \cdot 2 ab - 3 b (- 4 b^{2}) : a^{3} - a^{2} b - 10 a b^{2} + 12 b^{3}

= a^{3} - a^{2} b - 10 a b^{2} + 12 b^{3}

a (x + 1) - x - 1

- 7 x^{2} - 1 + x^{2} - x - 5
