Solution

expand

- x (7 x^{2} - 8 x - 3)

Solution

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

Solution steps

- x (7 x^{2} - 8 x - 3)

Apply the distributive law:

m (a + b + c) = ma + mb + m c

- x (7 x^{2} - 8 x - 3) = - x \cdot 7 x^{2} - x (- 8 x) - x (- 3)

= - x \cdot 7 x^{2} - x (- 8 x) - x (- 3)

Simplify

- x \cdot 7 x^{2} - x (- 8 x) - x (- 3) : - 7 x^{3} + 8 x^{2} + 3 x

= - 7 x^{3} + 8 x^{2} + 3 x
