Answer 2

Answer:

Given : x8 - 1

We can write this as :

=>(x4)² - (1)

Identity : a²-b² = (a - b)(a + b)

Here, a = x⁴, b=1

=>(x⁴ - 1)(x⁴ + 1)

We can write this as :

[(x²)² - (1)²](x⁴+ 1)

Identity : a²-b² = (a - b)(a + b)

Here, a = x², b = 1

=> (x² - 1)(x⁴+ 1)(x + 1)

We can write this as :

-:- [(x)² - (1)²] (x²+ 1)(x⁴+ 1)

Identity : a²-b² = (a - b)(a + b)

Here, a = x, b = 1

:- (x - 1)(x + 1)(x² + 1)(x⁴+ 1)
