RenĂ© Descartes - Wikipedia, the free encyclopedia - Jul 28th 2008, 04:28 AMcolby2152
Here is a link to the Rational Zeros Theorem. It basically gives the set of all possibilities of number that would satisfy $\displaystyle f(x)=0$

Descartes' Rule of Signs simply determines the number of possible solutions.

Rene Descartes was a French philosopher and mathematician who is known best for his works on the Cartesian coordinate system and his analytical geometry ideas provided the framework for Newton and Leibniz's Calculus. - Jul 28th 2008, 09:15 PMmagentaritaGreat...
