The Fundamental Theorem of Algebra

Lecture no. 24 from the course: Algebra II

The Fundamental Theorem of Algebra

Taught by Professor James A. Sellers | 31 min | Categories: The Great Courses Plus Online Mathematics Courses

Explore two additional tools for identifying the roots of polynomial equations: Descartes' rule of signs, which narrows down the number of possible positive and negative real roots; and the fundamental theorem of algebra, which gives the total of all roots for a given polynomial.
