Factoring quadratic trinomials
When asked to factor a quadratic equation such as 2x^2 - 7x -15, many students are uncomfortable with the guess and check method. I created this video to describe a 7 step method that requires NO GUESSING.

This is my son. Yes he was only 6 when we made this clip. And it's the best testimony I can give of my teaching and tutoring credentials.
This video checks the solution of the video for solving for x using the quadratic equation. It includes the steps for reducing a root that, when computed, does not come out to be a perfect square, yet must be used in the FOIL method of the polynomial...
This is a step-by-step Algebra instructional video showing how to find X using the Quadratic Formula.
Another example of changing a quadratic to vertex form using completing the square.
This video is example 1 of changing a quadratic from general form to vertex form using completing the square.
Video demonstrate how the quadratic equation is obtained by completing the square
Video shows how to use the method of completing the square to solve for the variable in a quadratic equation.
The video shows how to solve a quadratic equation by factoring, and this is a simple case when the coefficient of the variable with highest degree is equal to 1
This video is a follow-up to my 'How to solve a Quadratic Equation by Completing the Square' video. I go through more examples in this video of applying this useful tool to solve a quadratic equation.
In this tutorial video, I explain how to use the method of 'completing the square' to solve a quadratic equation. I go through the steps slowly and then I demonstrate with an example.
Step-by-step directions for solving a quadratic equation using the "Complete the Square" method.
