expand (2x-1)(-2x^2-7x-7)

expand

(2 x - 1) (- 2 x^{2} - 7 x - 7)

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

Solution steps

(2 x - 1) (- 2 x^{2} - 7 x - 7)

Distribute parentheses

= 2 x (- 2 x^{2}) + 2 x (- 7 x) + 2 x (- 7) - 1 \cdot (- 2 x^{2}) - 1 \cdot (- 7 x) - 1 \cdot (- 7)

Simplify

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

= - 4 x^{3} - 12 x^{2} - 7 x + 7

\frac{25}{35}

- 8 w^{2} + (- 7) w^{2}

\frac{- 6 i}{3 + 2 i}

1 \frac{1}{2} + 1 \frac{1}{3}
