Question

the factorization of x²-1 is​

Answer 1

(a+b)(a-b)=a^2+b^2

a=x b=1

x^2=x

so,(x+1)(x-1)

Answer 2

Answer:

(x + 1) (x - 1)

Step By Step Explanation:

Rewrite 1 as 1²

x² - 1²

Since both terms are perfect squares, factor using the difference of squares formula, a² − b² = (a + b)(a − b) where a = x and b = 1.

(x + 1) (x - 1)
