Показать описание
In this video, we compute the Galois group of a quartic polynomial whose Galois group is isomorphic to the dihedral group D_4. 

This is lecture 35 (part 2/3) of the lecture series offered by Dr. Andrew Misseldine for the course Math 4230 - Abstract Algebra II at Southern Utah University. A transcript of this lecture can be found at Dr. Misseldine's website or through his Google Drive at:
