Note: You can't go through algebra without seeing quadratic functions. The graphs of quadratic functions are parabolas; they tend to look like a smile or a frown. In this tutorial, get introduced to quadratic functions, look at their graphs, and see some examples of quadratic functions!ou can't go through algebra without seeing quadratic functions.

We would have to complete the square. I have a lesson on solving quadratics by completing the square, which explains the steps and gives examples of this process. It also shows how the Quadratic Formula is generated by this process. So I'll just do just one example of the process in this lesson.If you need further instruction, read the lesson at the above hyperlink. 1  Use completing the square to solve x2 â 4x â 8 = 0.t also shows how the Quadratic Formula is generated by this process.
