Examples in Galois Theory 3 - Polynomials of Prime Degree and Pairs of Nonreal Roots

Desvl at 
IntroductionIn the previous post we are convinced that the Galois group of a separable irreducible polynomial \(f\) can be realised as a subgroup of the symmetric group, the elements of which permute the roots of \(f\). We worked on cubic polynomials over a field with characteristic not equal to \(2……
