Demonstrates the use of the Quadratic Formula and compares the Formula to solving-by-factoring. ... For the Quadratic Formula to work, you must have your equation arranged in the form "(quadratic) = 0". Also, the "2a" in the denominator of the Formula is underneath everything above, not just the square root.

In this tutorial, we will be looking at solving a specific type of equation called the quadratic equation. The methods of solving these types of equations that we will take a look at are solving by factoring, by using the square root method, by completing the square, and by using the quadratic equation.
