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

expand

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

2 x^{4} - 3 x^{3} - 11 x^{2} - 16 x - 2

Solution steps

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

Distribute parentheses

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

Simplify

- x^{2} (- 2 x^{2}) - x^{2} \cdot 7 x - x^{2} \cdot 1 - 2 x (- 2 x^{2}) - 2 x \cdot 7 x - 2 x \cdot 1 - 2 (- 2 x^{2}) - 2 \cdot 7 x - 2 \cdot 1 : 2 x^{4} - 3 x^{3} - 11 x^{2} - 16 x - 2

= 2 x^{4} - 3 x^{3} - 11 x^{2} - 16 x - 2
