Web jacobi proved that, for every real quadratic form, there is an orthogonal diagonalization; Web for the quadratic form $x^tax; To enter f ( x) = 3 x 2, you can type 3*x^2 in the box for f ( x). R n r, so its derivative should be a 1 × n 1 × n matrix, a row vector. And it can be solved using the quadratic formula: That formula looks like magic, but you can follow the steps to see how it comes about. Sometimes the term biquadratic is used instead of quartic, but, usually, biquadratic function refers to a quadratic function of a square (or, equivalently, to the function defined by a quartic polynomial without terms of odd degree), having the form = + +. So, the discriminant of a quadratic form is a special case of the above general definition of a discriminant.
