Quadratic form
... This bilinear form BQ has the special property that B(x, x) = Q(x) for all x in V. When the characteristic of K is two so that 2 is not a unit, it is still possible to use a quadratic form to define a bilinear form B(x,y) = Q(x+y) − Q(x) − Q(y). However, Q(x) can no longer be recovered from this B i ...
