Sum & Product of Roots Quadratic Equation 5 Examples

I start by reviewing how to solve Quadratic Equations by Factoring at 1:28 and 3:44 Then we work through 3 examples evaluating expressions that involve solutions to a quadratic equation using the properties of sum of roots and the product of roots at 11:55 17:52 and 25:48 This relationship between the product and sum of roots and the coefficients of a polynomial was discovered by Francois Viete. Sum and Product of Roots of Polynomials Viete's Formula    • Sum and Product of Roots of Polynomials Vi...   Check out http://www.ProfRobBob.com, there you will find my lessons organized by chapters within each subject.
