expand (x^2-2x-2)(2x^2+3x-3)

expand

(x^{2} - 2 x - 2) (2 x^{2} + 3 x - 3)

2 x^{4} - x^{3} - 13 x^{2} + 6

Solution steps

(x^{2} - 2 x - 2) (2 x^{2} + 3 x - 3)

Distribute parentheses

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

Simplify

x^{2} \cdot 2 x^{2} + x^{2} \cdot 3 x + x^{2} (- 3) - 2 x \cdot 2 x^{2} - 2 x \cdot 3 x - 2 x (- 3) - 2 \cdot 2 x^{2} - 2 \cdot 3 x - 2 (- 3) : 2 x^{4} - x^{3} - 13 x^{2} + 6

= 2 x^{4} - x^{3} - 13 x^{2} + 6

\frac{m ^{3} n - m ^{2} n ^{2}}{n ^{2} - m ^{2}}

s (s + 1) (s^{2} + 6 s + 13)

\frac{9 !}{( 9 - 5 ) !}
