Lesson Summary:

In this lesson, the teacher explains how to solve for the zeros of a function using factoring by grouping. Instead of using regular factoring, which only works for quadratic equations, factoring by grouping can be used for equations with four terms. The teacher shows step-by-step how to factor out common terms and ultimately find the zeros of the function. By the end of the lesson, students will be able to use this method to find the zeros of any equation using factoring by grouping.

Lesson Description:

Finding the zeros of the function using factoring by grouping

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.

Questions answered by this video:
  • what do you mean by finding the zeros of the function?
  • What is the best way to factorise when there are 4 terms?
  • How would you check if your values of x to make the function equal 0 are correct ?
