    The answer is in the very wiki article that you cite.

    It's true, sorry!!!

    The formula is too complex that I didn't recognize at 1st vista.

    But exist in somewhere in the internet the matrix formula (already replaced by coefficients) for the quadratic, cubic and quartic discriminant?

    Yes, of course. The wiki link gives the general formula. So just take a specific ##n##.
    It also gives the formula for ##n=4##.
