Answer 1

Answer:

please mark my ans as the brainliest

Step-by-step explanation:

=(x-1)(x+1)(x^2+1)(x^4+1)

[using identity:a^2-b^2=(a+b)(a-b)]

=[(x-1)(x+1)](x^2+1)(x^4+1)

=(x^2-1)(x^2+1)(x^4+1)

=[(x^2-1)(x^2+1)](x^4+1)

=(x^4-1)(x^4+1)

=x^8-1(ans)

Answer 2

Step-by-step explanation:

$(x + 1)( x - 1)(x {2}^{} + 1)$

$( {x}^{2 } - {1}^{2} )( {x}^{2} + 1)$

$( {x}^{4} - 1)$
