Writing Standard Form of a Quadratic Equation
In this lesson, we learn how to find the standard form of a quadratic equation by looking at the graph. The standard form is easier to use and is in the form of x equals a times x minus h squared plus k. By identifying the vertex and a point on the graph, we can find the values for h, k, and a, which allows us to write the quadratic equation in standard form.

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
- For the function f(x)=(x-2)² state the coordinates of the vertex.
- For the function f(x)=(x-2)² state the equation of the axis of symmetry.
- For the function f(x)=-3(x+1)²-2 state the coordinates of the vertex.
- For the function f(x)=-3(x+1)²-2 state the equation of the axis of symmetry.
