We study Pfister neighbors and their characterization over fields of characteristic 2, where we include the case of singular forms. We give a somewhat simplified proof of a theorem of Fitzgerald which ...

Show answer Solving equations with quadratic graphs Graphs of quadratic functions can be used to solve equations. Example Draw the graph of y = 2 x 2 + 2 x 4 for values of –3 to 2.

A quadratic function has an equation of the form y = a x 2 + b x + c where b and/or c can be equal to zero, but a is not equal to zero. Its graph is a smooth symmetrical curve.

A good description of Least Squares Fit to Quadratic Data Part of a least squares fit involves solving three equations with three unknowns. Here is a description of using Excel's Solver to do this ...

Quadratic equations are polynomials, meaning strings of math terms. An expression like “x + 4” is a polynomial. They can have one or many variables in any combination, and the magnitude of them is ...

A method used by Kac in the study of Wiener functionals is adapted to the problem of calculating in closed form the joint moment generating functions of linear combinations of quadratic forms (not ...
