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

expand

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

6 x^{3} - 9 x^{2} - 22 x - 8

Solution steps

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

Distribute parentheses

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

Simplify

- 2 x (- 3 x^{2}) - 2 x \cdot 6 x - 2 x \cdot 8 - 1 \cdot (- 3 x^{2}) - 1 \cdot 6 x - 1 \cdot 8 : 6 x^{3} - 9 x^{2} - 22 x - 8

= 6 x^{3} - 9 x^{2} - 22 x - 8

(3 y^{2} z^{3})^{3} (z^{3} y^{4})^{- 2}

lo g_{10} (3.5)

\frac{x - 9}{x - 3}

\frac{x ^{2} - 9}{x ^{2} + 6 x + 9} \cdot \frac{3 x + 9}{3 x - 9}

lo g_{3} (3 \frac{1}{2})
