{{move|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:
A million lights are dancing
:''q('''x''')'' = '''''x'''''(''A'' '''''x''''')
where '''''y''''' = ''A'' '''''x''''' is the vector resulting from multiplying a matrix and a vector (a [[linear transformation]]) and '''''x''''' ('''''y''''') is the [[scalar product]] of vectors.
