expand (-4x+5)(3x^2-2x-1)

expand

(- 4 x + 5) (3 x^{2} - 2 x - 1)

- 12 x^{3} + 23 x^{2} - 6 x - 5

Solution steps

(- 4 x + 5) (3 x^{2} - 2 x - 1)

Distribute parentheses

= - 4 x \cdot 3 x^{2} - 4 x (- 2 x) - 4 x (- 1) + 5 \cdot 3 x^{2} + 5 (- 2 x) + 5 (- 1)

Simplify

- 4 x \cdot 3 x^{2} - 4 x (- 2 x) - 4 x (- 1) + 5 \cdot 3 x^{2} + 5 (- 2 x) + 5 (- 1) : - 12 x^{3} + 23 x^{2} - 6 x - 5

= - 12 x^{3} + 23 x^{2} - 6 x - 5

12 \frac{1}{2} - 2 \frac{1}{4} - 3 \frac{3}{8}

x^{2} + 6 x - 91

12 x^{2} - 41 x + 24

(\frac{4}{11})^{2}

\frac{\frac{2}{2}}{\frac{1}{2}}
