The Rule of Signs was first described by René Descartes in 1637, and is sometimes called Descartes' Rule of Signs. Descartes' Rule of Signs Scott E. Brodie. 1/1/99. In Descartes' revolutionary work, La Geometrie, as the discussion turns to the roots of polynomial equations, we find, without hint of a proof, the statement: Descartes' Rule of Signs. ZFB.

The rule gives an upper bound on the number of positive or negative roots, but does not specify the exact amount. Descartes’ Rule of Signs; Descartes’ Rule of Signs can be used to determine the number of positive real zeros, negative real zeros, and imaginary zeros in a polynomial function. Use Descartes rule of signs to determine the maximum number of possible real zeros of a polynomial function Solve real-world applications of polynomial equations. A vital implication of the Fundamental Theorem of Algebra is that a polynomial function of degree n will have n zeros in the set of complex numbers if we allow for multiplicities.

The number of positive real zeros is either P, or else P – k, where k is any even integer. 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]).
