Question

Heya!!!

The question is here

Factorize

${x}^{2} - 1$
Thanx

Answer 1

Given Equation is x^2 - 1.

= > x^2 - 1^2

We know that a^2 - b^2 = (a + b)(a - b)

= > (x + 1)(x - 1).


Hope this helps!

Answer 2

Hey there!

It's easy one!

$x^2 - 1\\\text{We can write 1 as }1^2\\=x^2-1^2\\\text{we know,}a^2-b^2 = (a+b)(a-b)\\=(x+1)(x-1)$

Hope It Helps You! :)
