It asserts that the number of positive roots is at most the number of sign changes in the sequence of polynomial's coefficients, and that the difference between these two numbers is always even.

In. Here's a striking theorem due to Descartes in 1637, often known as “Descartes' rule of signs”: The number of positive real roots of a polynomial is bounded by It asserts that the number of positive roots is at most the number of sign changes in the sequence of polynomial's coefficients (omitting the zero coefficients), and Descartes's rule of signs says that the number of positive roots of p(x) is equal. to the number of sign changes in the sequence a 0; a1;:::;an, or is less than this. According to Descartes' Rule of Signs, can the polynomial function have exactly 1 positive real zero, including any repeated zeroes? Choose your answer based 17 Jul 2018 It is important to remember that Descartes' rule of signs says that a polynomial has at least as many sign changes as it has positive real roots.
