- It has been proposed that this page, :Quadratic form, be titled, "quadratic form".
Quadratic forms are functions expressed as multivariable equations in linear algebra that have only combined power of two. When represented by matrices, they have a geometric significance as a shift or transformation in coordinates.
A quadratic form q(x) can be written as:
- q(x) = x(A x)
