expand (-3x-5)(3x^2+x-1)

expand

(- 3 x - 5) (3 x^{2} + x - 1)

- 9 x^{3} - 18 x^{2} - 2 x + 5

Solution steps

(- 3 x - 5) (3 x^{2} + x - 1)

Distribute parentheses

= - 3 x \cdot 3 x^{2} - 3 xx - 3 x (- 1) - 5 \cdot 3 x^{2} - 5 x - 5 (- 1)

Simplify

- 3 x \cdot 3 x^{2} - 3 xx - 3 x (- 1) - 5 \cdot 3 x^{2} - 5 x - 5 (- 1) : - 9 x^{3} - 18 x^{2} - 2 x + 5

= - 9 x^{3} - 18 x^{2} - 2 x + 5

\frac{x ^{2} - 1}{x ^{2} - 4 x - 5}

\frac{9}{2} - 9

400 0^{2}

\frac{1}{2} \times \frac{1}{6}

- 2 (3 x + 1) (x + 2) (x - 3)
