Review of: "Solution of Schrödinger equation for two different potentials using extended Nikiforov-Uvarov method and polynomial solutions of biconfluent Heun equation"

We analyse the analytical eigenvalues obtained by means of the so-called extended Nikiforov-Uvarov method for two radial potentials.We show that in one case the analytical expression is extremely inaccurate.In the other case, the analytical expression exhibits a wrong behaviour with respect to the potential parameters.It seems that the approach proposed by the authors is inadequate for the treatment of this kind of quantum-mechanical models.
