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

expand

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

3 x^{3} - 10 x^{2} - 14 x - 4

Solution steps

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

Distribute parentheses

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

Simplify

3 x x^{2} + 3 x (- 4 x) + 3 x (- 2) + 2 x^{2} + 2 (- 4 x) + 2 (- 2) : 3 x^{3} - 10 x^{2} - 14 x - 4

= 3 x^{3} - 10 x^{2} - 14 x - 4

x + \frac{1}{x}

3 \cdot 1

\frac{3}{x + 7} - \frac{7 x}{x ^{2} + 9 x + 14}

- 25 + - 40 + 81 - - 10

\frac{1}{3} + \frac{1}{12}
