Given n ∈N and p prime number and consider the polynomial f (x) = xn (xn-2)+1-p
1)Prove that f (x) is irreducible in Q [x] 2) If n = 1 and p = 3, find Q [x] / f (x)) 3) Show that indeed Q [x] / (f (x)) is a field in the previous paragraph
PLEASE answer all subsections
First to prove the irreducibility of f, we will use the property of a prime number, and further , we wil prove field axiom existence of inverse.
And hence we can easily conclude that
Q[x] / (f(x)) does not have any zero divisor elements.
Thus , this is a field.
