expand (4-b)(5b^2+5b-4)

expand

(4 - b) (5 b^{2} + 5 b - 4)

- 5 b^{3} + 15 b^{2} + 24 b - 16

Solution steps

(4 - b) (5 b^{2} + 5 b - 4)

Distribute parentheses

= 4 \cdot 5 b^{2} + 4 \cdot 5 b + 4 (- 4) - b \cdot 5 b^{2} - b \cdot 5 b - b (- 4)

Simplify

4 \cdot 5 b^{2} + 4 \cdot 5 b + 4 (- 4) - b \cdot 5 b^{2} - b \cdot 5 b - b (- 4) : - 5 b^{3} + 15 b^{2} + 24 b - 16

= - 5 b^{3} + 15 b^{2} + 24 b - 16

(\frac{1}{2})^{\frac{3}{2}}

22 - 12 = 2 (x - 1)

\frac{1}{4} - [\frac{3}{2} (\frac{4}{3} \div \frac{3}{4}) + \frac{1}{2}]

(2^{2})^{4}

\frac{10 n}{2 ( n ^{- 3} ) ^{4}}
