expand-2x(x^2-3)

Solution

expand

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

Solution

- 2 x^{3} + 6 x

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

- 2 x (x^{2} - 3) = - 2 x x^{2} - (- 2 x) \cdot 3

= - 2 x x^{2} - (- 2 x) \cdot 3

Simplify

- 2 x x^{2} - (- 2 x) \cdot 3 : - 2 x^{3} + 6 x

= - 2 x^{3} + 6 x
