Thank you for all the examples! There is surely other good teaching material on this topic on Youtube available too but much of that seem to lack a sufficient number of examples. It is good to practise, over and over, through all these examples.

Thanks so much!
I didn't expect you to have only this much subs with such great explanations

Nice video on Galois group. By the way which software tool you used for the whiteboard.

Hello, I believe the cubic resolvent should be R_3(x) = x^3 -4bx + a^2. I’m getting this definition from page 308 of algebra by Papantonopoulpou. Please let my know your thoughts.
