expand (3x+1)(3x^2-6x-8)

expand

(3 x + 1) (3 x^{2} - 6 x - 8)

9 x^{3} - 15 x^{2} - 30 x - 8

Solution steps

(3 x + 1) (3 x^{2} - 6 x - 8)

Distribute parentheses

= 3 x \cdot 3 x^{2} + 3 x (- 6 x) + 3 x (- 8) + 1 \cdot 3 x^{2} + 1 \cdot (- 6 x) + 1 \cdot (- 8)

Simplify

3 x \cdot 3 x^{2} + 3 x (- 6 x) + 3 x (- 8) + 1 \cdot 3 x^{2} + 1 \cdot (- 6 x) + 1 \cdot (- 8) : 9 x^{3} - 15 x^{2} - 30 x - 8

= 9 x^{3} - 15 x^{2} - 30 x - 8
