The Quadratic Formula is a great method for solving any quadratic equation. These step by step examples and practice problems will guide you through the process of using the quadratic formula.

The Quadratic Formula Before the method of completing the square was developed, only very limited types of quadratic equations could be solved. This method eliminated those limitations, allowing the solutions of any quadratic equation to be found. This lecture shows how the 'quadratic formula' can be derived from the process of completing the square, and show why the quadratic formula is so useful.

This idea came from Sarah when I saw her quadratic formula template. I teach this topic a little different so I modified it to fit the method I use in the classroom. Below you will notice with more time I have changed these templates again to hopefully make them more understandable to my students.

Quadratic Equation Formula denoted as second-degree algebraic expressions, take the form ax2+bx+ c = 0. The term "quadratic" originates from the Latin word "quadratus," meaning square.
