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

expand

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

9 x^{3} + 27 x^{2} + 5 x - 8

Solution steps

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

Distribute parentheses

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

Simplify

3 x \cdot 3 x^{2} + 3 xx + 3 x (- 1) + 8 \cdot 3 x^{2} + 8 x + 8 (- 1) : 9 x^{3} + 27 x^{2} + 5 x - 8

= 9 x^{3} + 27 x^{2} + 5 x - 8

e^{x} \times (- e^{- x})

45 \times 2

8 \times \frac{3}{4}

3 \frac{8 x ^{3}}{27}

\frac{9}{12}
