1. ## Describe the Difference

In simple words, can anyone tell me what is the basic difference between Descartes' Rule of Signs and the Rational Zero Theorem? Is there a connection between the two?

Thanks

P.S. Who is Descartes anyway?

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.
