Solving Quadratic Equations with Quadratic Formula 3 Examples

I work through three examples of solving a Quadratic Equation using the Quadratic Formula. Example 1 at 3:40 has no solution Example 2 at 9:04 reviews how to simplify radicals and give your answer in exact form. Example 3 at 15:20 shows why you do not want to divide away a variable. I then show how to work the problem by factoring and using the Quadratic Formula. Along the way I also give some cautionary notes to help make sure you don't make sign errors or divide away one of your answers.
