expand 3(x+h)^3

Solution

expand

3 (x + h)^{3}

Solution

3 x^{3} + 9 x^{2} h + 9 x h^{2} + 3 h^{3}

Solution steps

3 (x + h)^{3}

Expand

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

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

Distribute parentheses

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

Simplify

3 x^{3} + 3 \cdot 3 x^{2} h + 3 \cdot 3 x h^{2} + 3 h^{3} : 3 x^{3} + 9 x^{2} h + 9 x h^{2} + 3 h^{3}

= 3 x^{3} + 9 x^{2} h + 9 x h^{2} + 3 h^{3}
