About This Lesson

In this lesson, we will:
**study tips** and **math video**
below will explain more.

- Learn what is the vertex of a quadratic equation.
- 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.

Tip #1

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.

Tip #1 - Vertex Formula

The formula to find the x-coordinate of the vertex is
shown below:

Where **a** and **b** are the coefficients
in the general quadratic equation shown below:
