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

expand

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

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

Solution steps

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

Distribute parentheses

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

Simplify

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

= - 4 x^{3} - 4 x^{2} - 3 x - 1
