expand 2D((s+1)(s-1))

Solution

expand

2 D ((s + 1) (s - 1))

Solution

2 D s^{2} - 2 D

Solution steps

2 D ((s + 1) (s - 1))

Remove parentheses:

(a) = a

= 2 D (s + 1) (s - 1)

Expand

(s + 1) (s - 1) : s^{2} - 1

= 2 D (s^{2} - 1)

Expand

2 D (s^{2} - 1) : 2 D s^{2} - 2 D

= 2 D s^{2} - 2 D
