Solution

expand

- 4 x^{2} (3 x - 7)

Solution

- 12 x^{3} + 28 x^{2}

Solution steps

- 4 x^{2} (3 x - 7)

Apply the distributive law:

a (b - c) = ab - a c

- 4 x^{2} (3 x - 7) = - 4 x^{2} \cdot 3 x - (- 4 x^{2}) \cdot 7

= - 4 x^{2} \cdot 3 x - (- 4 x^{2}) \cdot 7

Simplify

- 4 x^{2} \cdot 3 x - (- 4 x^{2}) \cdot 7 : - 12 x^{3} + 28 x^{2}

= - 12 x^{3} + 28 x^{2}
