![](/common/images/spacer.gif) Using homotopy continuation methods such as the fixed point and the Newton homotopy methods, one can find all real solutions of a polynomial equation. Two examples are presented here. In notebook Homotopy_Polynomial2.nb, we also reproduce Figure 4 in the excellent paper by M. Kuno and J. D. Seader, Computing All Real Solutions to Systems of Nonlinear Equations with a Global Fixed-Point Homotopy, Ind. Eng. Chem. Res., 1988, 27, 1320-1329.
