factorize [tex] x^{22} -3x^{11} + 2 [/tex](adsbygoogle = window.adsbygoogle || []).push({});

right so I have p(x) = (x^11 -2)(x^11 - 1)

(x^11 -2) satifies eisentstein, obviously x-1 is a factor of the second factor. Long division reaps [tex] x^{10} + x^9 +...+x + 1 [/tex]

the solution asserts that this is also irreducible, but I do not see this?? Is this one of those where you substitue x for y+1??
