expand (-x-3)(2x^2+5x+8)

expand

(- x - 3) (2 x^{2} + 5 x + 8)

- 2 x^{3} - 11 x^{2} - 23 x - 24

Solution steps

(- x - 3) (2 x^{2} + 5 x + 8)

Distribute parentheses

= - x \cdot 2 x^{2} - x \cdot 5 x - x \cdot 8 - 3 \cdot 2 x^{2} - 3 \cdot 5 x - 3 \cdot 8

Simplify

- x \cdot 2 x^{2} - x \cdot 5 x - x \cdot 8 - 3 \cdot 2 x^{2} - 3 \cdot 5 x - 3 \cdot 8 : - 2 x^{3} - 11 x^{2} - 23 x - 24

= - 2 x^{3} - 11 x^{2} - 23 x - 24

4 \times \frac{1}{2}

(f^{3} - 5 f + 25) - (4 f^{2} - 12 f + 9)

8 \frac{2}{3}

(x + 4)^{4}

5 x + 15
