expand 2(a-3)^3

Solution

expand

2 (a - 3)^{3}

Solution

2 a^{3} - 18 a^{2} + 54 a - 54

Solution steps

2 (a - 3)^{3}

Expand

(a - 3)^{3} : a^{3} - 9 a^{2} + 27 a - 27

= 2 (a^{3} - 9 a^{2} + 27 a - 27)

Distribute parentheses

= 2 a^{3} + 2 (- 9 a^{2}) + 2 \cdot 27 a + 2 (- 27)

Simplify

2 a^{3} + 2 (- 9 a^{2}) + 2 \cdot 27 a + 2 (- 27) : 2 a^{3} - 18 a^{2} + 54 a - 54

= 2 a^{3} - 18 a^{2} + 54 a - 54
