factor (a^2+1)-(a^2-1)

Solution

factor

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

Solution

2

Solution steps

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

Remove parentheses:

(a) = a

= a^{2} + 1 - (a^{2} - 1)

- (a^{2} - 1) = - (a + 1) (a - 1)

= a^{2} + 1 - (a + 1) (a - 1)

Expand

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

= a^{2} + 1 - a^{2} + 1

Simplify

a^{2} + 1 - a^{2} + 1 : 2

= 2
