Lesson Summary:

In this lesson, the box method is introduced as a way to find the zeros of a trinomial function algebraically. The method involves setting up a box and factoring the trinomial into two linear factors. Using the diamond method, the box is completed, and the two possible zeros are determined by setting each factor equal to zero. The lesson also touches on alternative methods like the square method.

Finding the zeros of a trinomial function using box method

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
