摘要：Real solutions representation for the cubic equation with real coefficients in a parametric form is given. The dependence
of the solutions on the equation coefficients and the bifurcation conditions for these solutions are studied. In the parametric
space regions with one and three real solutions are considered. Using parametric representations of the cubic equation
solutions, the stability and bifurcation conditions of the equilibrium states for the thermodynamic systems described by
the Landau-type kinetic potential are analyzed.
