expand-2(x+h)^3

Solution

expand

- 2 (x + h)^{3}

Solution

- 2 x^{3} - 6 x^{2} h - 6 x h^{2} - 2 h^{3}

Solution steps

- 2 (x + h)^{3}

Expand

(x + h)^{3} : x^{3} + 3 x^{2} h + 3 x h^{2} + h^{3}

= - 2 (x^{3} + 3 x^{2} h + 3 x h^{2} + h^{3})

Distribute parentheses

= - 2 x^{3} - 2 \cdot 3 x^{2} h - 2 \cdot 3 x h^{2} - 2 h^{3}

Simplify

- 2 x^{3} - 2 \cdot 3 x^{2} h - 2 \cdot 3 x h^{2} - 2 h^{3} : - 2 x^{3} - 6 x^{2} h - 6 x h^{2} - 2 h^{3}

= - 2 x^{3} - 6 x^{2} h - 6 x h^{2} - 2 h^{3}
