Factoring out the GCF
At about the 0:16 mark, the teacher says factoring out the greatest common denominator; he should have said the greatest common factor.
At about the 1:39 mark, after factoring out a 7x, the teacher writes xy for the first term in parentheses; it should be 2xy.
In this lesson, we learn about factoring out the greatest common factor (GCF) of a set of terms. The teacher explains that the GCF is the largest number of variables that goes into every term that can be divided into every term. Through three examples, the teacher shows how to factor out the GCF by dividing out the common numbers and variables. The lesson ends with a reminder to check your work using the distributive property.
Factoring Blitz #1 - Factoring out common factors
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.
