expand 3(8-4b)^3

expand

3 (8 - 4 b)^{3}

1536 - 2304 b + 1152 b^{2} - 192 b^{3}

Solution steps

3 (8 - 4 b)^{3}

Expand

(8 - 4 b)^{3} : 512 - 768 b + 384 b^{2} - 64 b^{3}

= 3 (512 - 768 b + 384 b^{2} - 64 b^{3})

Distribute parentheses

= 3 \cdot 512 + 3 (- 768 b) + 3 \cdot 384 b^{2} + 3 (- 64 b^{3})

Simplify

3 \cdot 512 + 3 (- 768 b) + 3 \cdot 384 b^{2} + 3 (- 64 b^{3}) : 1536 - 2304 b + 1152 b^{2} - 192 b^{3}

= 1536 - 2304 b + 1152 b^{2} - 192 b^{3}

\frac{8}{9} - \frac{1}{2}

\frac{x}{x + 1} + \frac{2}{x - 3}

- 4 x^{- 6}

6 m (4 m^{3} + 23)
