2010-11-15 · The rule of signs of Descartes implies that for any g ∈ R greaterorequalslant0 [x], the number S(fg) of changes of signs in fg is at least R(fg) = R(f ). Therefore, Theorem 1.1 can be simply written as R(f ) = min g∈R greaterorequalslant0 [x] S(fg).Notethatthepolynomialg of the theorem can be used to certify that f has no more than R(f ) positive roots. Descartes Rule of Signs on Brilliant, the largest community of math and science problem solvers. Before using the Rule of Signs the polynomial must have a constant term (like "+2" or "−5") If it doesn't, then just factor out x until it does. Example: 2x 4 + 3x 2 − 4x Descartes' rule of sign is used to determine the number of real zeros of a polynomial function. It tells us that the number of positive real zeroes in a polynomial function f(x) is the same or less than by an even numbers as the number of changes in the sign of the coefficients.

In mathematics, Descartes' rule of signs, first described by René Descartes in his work La Géométrie, is a technique for getting information on the number of positive real roots of a polynomial. 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. This implies, in particular, that if the number of sign changes is zero or one, then there Descartes' Rule of Signs is a useful help for finding the zeroes of a polynomial, assuming that you don't have the graph to look at. This topic isn't so useful if you have access to a graphing calculator because, rather than having to do guess-n-check to find the zeroes (using the Rational Roots Test , Descartes' Rule of Signs, synthetic division , and other tools), you can just look at the picture on the screen.

Descartes’ Rule of Signs states that the number of positive roots of a polynomial p(x) with real coe cients does not exceed the number of sign changes of the nonzero coe cients of p(x). More precisely, the number of sign changes minus the number of positive roots is a multiple of two.1

The classical rule of signs due to Descartes provides an elementary upper bound for the number of positive zeros of a polynomial, namely, the number of sign changes of its coe cients. Since its publication in Descartes’ monumental La Géométrie in 1637, there has been a substantial body of research on the rule (see, for example, [1,5– 8,10]).

These bounds on the number of roots count with multiplicity. Descartes' algorithm is simple. Write a polynomial with its terms in ascending (or descending) degree order. 2010-11-15 · The rule of signs of Descartes implies that for any g ∈ R greaterorequalslant0 [x], the number S(fg) of changes of signs in fg is at least R(fg) = R(f ).
