Galois Theory (almost done)
Before the lecture Motivation My motivation was to understand why there is no solution in radicals to general polynomial equations of degree five or higher with arbitrary coefficients (Abel-Ruffini theorem).
I knew the fact but never had a chance to learn it. But I was so curious about it these days, and decided to check.
About learning material YouTube video “Visual Group Theory - Lecture 6” was easy to understand.
