expand (-2+x)^3

Solution

expand

(- 2 + x)^{3}

Solution

- 8 + 12 x - 6 x^{2} + x^{3}

Solution steps

(- 2 + x)^{3}

Apply Perfect Cube Formula:

(a + b)^{3} = a^{3} + 3 a^{2} b + 3 a b^{2} + b^{3}

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

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

Simplify

(- 2)^{3} + 3 (- 2)^{2} x + 3 (- 2) x^{2} + x^{3} : - 8 + 12 x - 6 x^{2} + x^{3}

= - 8 + 12 x - 6 x^{2} + x^{3}
