Given : X^2 - 1

It is in the form of a^2 - b^2 = ( a+ b) ( a - b)

so, your answer is ( x + 1 ) ( x - 1 )

Answer 2

Given :  $equation \ is , \ x^2-1$  

for middle term splitting, add and subtract x in the equation,

⇒ $x^2 +x - x - 1$

⇒ $x(x+1) \ - 1(x+1)$

  ∴ $(x + 1)(x - 1)$

______________(or)_______________

We have,  $a^2-b^2 = (a+b)(a-b)$

  ∴  $x^2 - 1^2 = (x+1)(x-1)$
