Solution

expand

- 7 x (x^{2} + 6 x - 5)

Solution

- 7 x^{3} - 42 x^{2} + 35 x

Solution steps

- 7 x (x^{2} + 6 x - 5)

Apply the distributive law:

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

- 7 x (x^{2} + 6 x - 5) = - 7 x x^{2} - 7 x \cdot 6 x - 7 x (- 5)

= - 7 x x^{2} - 7 x \cdot 6 x - 7 x (- 5)

Simplify

- 7 x x^{2} - 7 x \cdot 6 x - 7 x (- 5) : - 7 x^{3} - 42 x^{2} + 35 x

= - 7 x^{3} - 42 x^{2} + 35 x
