Abstract
We consider real univariate degree real-rooted polynomials with non-vanishing coefficients. Descartes' rule of signs implies that such a polynomial has positive and negative roots counted with multiplicity, where and are the numbers of sign changes and sign preservations in the sequence of its coefficients, . For , we give the exhaustive answer to the question: When the moduli of all roots are distinct and arranged on the real positive half-axis, in which positions can the moduli of the negative roots be depending on the signs of the coefficients?
