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

expand

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

- 12 x^{3} - 5 x^{2} + 7 x + 3

Solution steps

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

Distribute parentheses

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

Simplify

- 4 x \cdot 3 x^{2} - 4 x (- x) - 4 x (- 1) - 3 \cdot 3 x^{2} - 3 (- x) - 3 (- 1) : - 12 x^{3} - 5 x^{2} + 7 x + 3

= - 12 x^{3} - 5 x^{2} + 7 x + 3

\frac{9 x y ^{2}}{25 x y}

3 w^{2} - 10 w + 8

1 \frac{1}{2} \div 3

1 0^{n + 1} (n + 1)

5 x (2 x + 7) + 4 x
