A generalization of the original Jordan - von Neumann theorem

The problem of the representability of quadratic functionals (acting on modules over unital complex *-algebras), by sesquilinear forms, is generalized by weakening the homogeneity equation. The corresponding representation theorem can be considered a generalization of (the original form of) the classical Jordan - von Neumann characterization of complex inner product spaces.
