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 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...
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.
