Within the framework of ansatz method, we investigate the exact closed-form solutions of the time independent Schrodinger equation for a two-dimensional anharmonic potential having sextic-type anharmonicity [say V(x, y) = Sigma(6)(ij-0)a(ij)x(i)y(j), with 1 <= i + j <= 6]. By imposing few restrictions on ansatz parameters and at the cost of some constraints on potential parameters, the ground state as well as excited states solutions are obtained.
