expand (x-3)(-2x^2-2x-9)

expand

(x - 3) (- 2 x^{2} - 2 x - 9)

- 2 x^{3} + 4 x^{2} - 3 x + 27

Solution steps

(x - 3) (- 2 x^{2} - 2 x - 9)

Distribute parentheses

= x (- 2 x^{2}) + x (- 2 x) + x (- 9) - 3 (- 2 x^{2}) - 3 (- 2 x) - 3 (- 9)

Simplify

x (- 2 x^{2}) + x (- 2 x) + x (- 9) - 3 (- 2 x^{2}) - 3 (- 2 x) - 3 (- 9) : - 2 x^{3} + 4 x^{2} - 3 x + 27

= - 2 x^{3} + 4 x^{2} - 3 x + 27
