expand [(x+1)(x-1)]2

Solution

expand

[(x + 1) (x - 1)] 2

Solution

2 x^{2} - 2

Solution steps

((x + 1) (x - 1)) \cdot 2

Remove parentheses:

(a) = a

= (x + 1) (x - 1) \cdot 2

= 2 (x + 1) (x - 1)

Expand

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

= 2 (x^{2} - 1)

Expand

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

= 2 x^{2} - 2
