Using Descartes Rule of Signs to determine possible number of solutions

The video tutorial explains the rational zero test and Descartes' rule of signs, focusing on determining possible real and complex zeros in polynomials. It covers quadratic solutions, including real and complex possibilities, and extends to higher degree polynomials. The tutorial demonstrates using F(-X) to find negative real zeros and employs a table to organize possible solutions, emphasizing understanding over exact answers.
