expand (3b-2)(4b^2+8b+7)

expand

(3 b - 2) (4 b^{2} + 8 b + 7)

12 b^{3} + 16 b^{2} + 5 b - 14

Solution steps

(3 b - 2) (4 b^{2} + 8 b + 7)

Distribute parentheses

= 3 b \cdot 4 b^{2} + 3 b \cdot 8 b + 3 b \cdot 7 - 2 \cdot 4 b^{2} - 2 \cdot 8 b - 2 \cdot 7

Simplify

3 b \cdot 4 b^{2} + 3 b \cdot 8 b + 3 b \cdot 7 - 2 \cdot 4 b^{2} - 2 \cdot 8 b - 2 \cdot 7 : 12 b^{3} + 16 b^{2} + 5 b - 14

= 12 b^{3} + 16 b^{2} + 5 b - 14

- 6 x^{2} - x + 7

(\frac{y ^{- 3}}{y ^{3}})^{2}

\frac{3}{4} \cdot \frac{5}{6}

20 c^{3} + 22 c^{4}

(x + 5)^{2} = - 4
