expand-2x^2(x+4)

Solution

expand

- 2 x^{2} (x + 4)

Solution

- 2 x^{3} - 8 x^{2}

Solution steps

- 2 x^{2} (x + 4)

Apply the distributive law:

a (b + c) = ab + a c

- 2 x^{2} (x + 4) = - 2 x^{2} x - 2 x^{2} \cdot 4

= - 2 x^{2} x - 2 x^{2} \cdot 4

Simplify

- 2 x^{2} x - 2 x^{2} \cdot 4 : - 2 x^{3} - 8 x^{2}

= - 2 x^{3} - 8 x^{2}
