It will be proven that if a gauge-invariant Lagrangian density having the local form L=L(gij;Ai;Ai,j) is such that its Euler–Lagrange equations Ei(L)=0 have the same set of solutions as Ei(L0)=0, where L0=g1/2FijFij, then L and cL0 are equivalent for same constant c, i.e., Ei(L)=Ei(cL0). From a previous result it follows that L=cL0+D+eg1/2, where D is a divergence and e is a constant.
