In this lesson, we will learn how to find
the vertex of a quadratic equation.
About This Lesson
In this lesson, we will:
Learn what is the vertex of a
Learn the formula to find the
x-coordinate of the vertex.
See some examples on using the formula to
find the coordinates of the vertex.
The study tips and math video
below will explain more.
The general quadratic equation is given as:
Where a, b and c are the coefficients of each term respectively. Now, the graph of a
quadratic equation will always have a highest point or
a lowest point depending on the value of a. This
point is called the Vertex. The pictures below will illustrate this.
