expand (s-4)(2s+2)(s^2-2)

expand

(s - 4) (2 s + 2) (s^{2} - 2)

2 s^{4} - 6 s^{3} - 12 s^{2} + 12 s + 16

Solution steps

(s - 4) (2 s + 2) (s^{2} - 2)

Expand

(s - 4) (2 s + 2) (s^{2} - 2) : (2 s^{2} - 6 s - 8) (s^{2} - 2)

= (2 s^{2} - 6 s - 8) (s^{2} - 2)

Distribute parentheses

= 2 s^{2} s^{2} + 2 s^{2} (- 2) - 6 s s^{2} - 6 s (- 2) - 8 s^{2} - 8 (- 2)

Simplify

2 s^{2} s^{2} + 2 s^{2} (- 2) - 6 s s^{2} - 6 s (- 2) - 8 s^{2} - 8 (- 2) : 2 s^{4} - 6 s^{3} - 12 s^{2} + 12 s + 16

= 2 s^{4} - 6 s^{3} - 12 s^{2} + 12 s + 16

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

\frac{6}{61}

(x + 7)^{2} - 6 (x + 7) - 2

(x + 7)^{2} - 6 (x + 7) - 4

11 x^{2}
