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

expand

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

- x^{4} - 8 x^{3} - 2 x^{2} - 7 x + 14

Solution steps

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

Distribute parentheses

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

Simplify

- x^{2} x^{2} - x^{2} \cdot 7 x - x^{2} (- 7) - x x^{2} - x \cdot 7 x - x (- 7) - 2 x^{2} - 2 \cdot 7 x - 2 (- 7) : - x^{4} - 8 x^{3} - 2 x^{2} - 7 x + 14

= - x^{4} - 8 x^{3} - 2 x^{2} - 7 x + 14

(2 x + 5 y) \cdot (2 x + 5 y)

3 \frac{1}{4} + \frac{2}{4}

\frac{1}{6} π

\frac{6 x ^{3} y ^{2} - 4 x ^{2} y ^{3} - 8 x y ^{3}}{- 2 x ^{2} y ^{3}}

- \frac{5}{3} - 1
