How to Solve Quadratic Equations using the Quadratic Formula

This tutorial explains how to use the quadratic formula to solve quadratic equations. It covers examples with two real solutions, one real solution, and no real solutions (two complex or imaginary solutions). It also covers quadratic equations in non standard form, and shows how to verify/check the solutions. In addition, it discuss the discriminant of a quadratic equation and how it determines the number of solutions.
