Sum and Product of Roots of Polynomials Viete's Formula

I show you the formulas for the Sum and Product of Roots for Quadratic and Cubic Equations. Then we looked at the general formula developed by Francois Viete and use that to work through 7 examples at 9:44 11:33 12:34 13:47 16:18 22:03 25:36 Sum & Product of Roots Quadratic Equation 5 Examples    • Sum & Product of Roots Quadratic Equation ...   Check out http://www.ProfRobBob.com, there you will find my lessons organized by chapters within each subject.
