Discriminant - Wikipedia, the free encyclopedia
My questions are in the topic "Discriminant of a polynomial".
How to prove that the discriminant of a polynomial P(x) is equal to the determinant of the (2n − 1)(2n − 1) matrix.
And why the the determinant of this (2n − 1)(2n − 1) matrix is equal to the resultant of P(x) and P'(x).

Please give me some hints or tell me where I can find the detail proofs.
Thank You!!!
