Descartes' Rule of Signs tells you that there could be four positive roots, and two negative roots, and any pair of those positive and negative roots could be replaced by a pair of complex conjugates. In actuality, that function has two positive, two negative and two complex roots, but Descartes isn't as precise as that.
