How to Graph a Quadratic Equation

This video shows three examples of solutions of a quadratic equation on a graph. When there is a parabola that crosses the x axis two times, each intersect will be a solution. When there is a parabola that intersects the x axis only once, there is only one solution, which is where the vertex touches the x axis. When the parabola does not touch the x axis, there are no real solutions, or there are two complex solutions.
