Quick explanation of Descartes rule of signs

The video tutorial explains Descartes' Rule of Signs, which helps determine the number of real positive and negative zeros in a polynomial. It describes how to find positive real zeros by counting sign changes between monomials and adjusting by an even number. The process for finding negative real zeros involves evaluating F(-X). The tutorial also discusses the fundamental theorem of algebra, which states that a polynomial must have a certain number of zeros, including complex zeros that occur in pairs.
