expand (3x+1)(2x^2-2x-9)

expand

(3 x + 1) (2 x^{2} - 2 x - 9)

6 x^{3} - 4 x^{2} - 29 x - 9

Solution steps

(3 x + 1) (2 x^{2} - 2 x - 9)

Distribute parentheses

= 3 x \cdot 2 x^{2} + 3 x (- 2 x) + 3 x (- 9) + 1 \cdot 2 x^{2} + 1 \cdot (- 2 x) + 1 \cdot (- 9)

Simplify

3 x \cdot 2 x^{2} + 3 x (- 2 x) + 3 x (- 9) + 1 \cdot 2 x^{2} + 1 \cdot (- 2 x) + 1 \cdot (- 9) : 6 x^{3} - 4 x^{2} - 29 x - 9

= 6 x^{3} - 4 x^{2} - 29 x - 9

\frac{2}{x} + \frac{3}{x + 5}

0 \times 2

5 x \times 2 x
