(x-1)(x+1)(x^2 + 1)(x^4 + 1)
use the formula : a^2 - b^2 = (a-b)(a+b)
use the formula : a^2 - b^2 = (a-b)(a+b)

That's wrong answer.
It’s wrong... how can x^8 be spliited into x^6^2?
the correct one is (x^4)^2
now split it further using a^2-b^2 formula...
yea ...
oh Yaa thanks
it was a mistake on my part
Sorry.... but you can further factorise it by splitting x^4-1 to (x^2)^2-1^2, so the final answer would be (x-1)(x+1)(x^2+1)(x^4 +1).....
