expand (-3x-4)(x^2+3x-5)

expand

(- 3 x - 4) (x^{2} + 3 x - 5)

- 3 x^{3} - 13 x^{2} + 3 x + 20

Solution steps

(- 3 x - 4) (x^{2} + 3 x - 5)

Distribute parentheses

= - 3 x x^{2} - 3 x \cdot 3 x - 3 x (- 5) - 4 x^{2} - 4 \cdot 3 x - 4 (- 5)

Simplify

- 3 x x^{2} - 3 x \cdot 3 x - 3 x (- 5) - 4 x^{2} - 4 \cdot 3 x - 4 (- 5) : - 3 x^{3} - 13 x^{2} + 3 x + 20

= - 3 x^{3} - 13 x^{2} + 3 x + 20

\frac{2}{6 x - 30} + \frac{7}{x - 5}

8 (9 t + 8) + 7 t

\frac{200}{100}

- \frac{1}{2} \cdot (- 1)

42 \times 2
