Discriminant - Wikipedia, the free encyclopedia
My questions are in the topic "Discriminant of a polynomial".
How to prove that the of a polynomial is equal to the of the (2n − 1)×(2n − 1) matrix.
And why the the of this (2n − 1)×(2n − 1) matrix is equal to the of and .
Please give me some hints or tell me where I can find the detail proofs.
