About this lesson
Welcome to the world of Quadratic Equations and the Quadratic Formula. In a previous video we looked at how the formula could be used to find the solutions to a whole range of problems. But it has a much more powerful use. Well, the part under the square root! The discriminant is an awesome way to find the number of solutions to a quadratic equation. We can use it to find if there are one, two or no solutions. It's also helpful when trying to find the axis of symmetry! So much fun in such a short lesson.
