To find a subfield, look for elements that remain invariant under a specific subgroup of automorphisms. Resources for Solutions Dummit And Foote Solutions Chapter 14

I should mention some key theorems: Fundamental Theorem of Galois Theory, which is the bijective correspondence between intermediate fields and subgroups of the Galois group. Also, the characterization of Galois extensions via their Galois group being the automorphism group of the field over the base field. Linking the solvability of a group to the
