We present exact analytical expressions of all the energy eigenstates and eigenvalues in terms of an unknown parameter λ for the model describing interactions among three bosonic modes without using the assumption of the Bethe anzatz. We also derive the explicit expression of a polynomial whose roots give the concrete values of the parameter λ.
