Abstract
In this paper the Decomposition Theorem for functional equations is shown. As an application of this Theorem the two times continuously differentiable solution of the functional equation G1(x(x+y))+F1(y) = G2(y(x+y))+F2(y) can be given with unknown functions ... where the Equation is fulfilled for all ... .
