The video tutorial explains how to factor a polynomial expression by identifying the greatest common factor (GCF) of its terms. It begins with an introduction to the problem and proceeds to find the GCF by examining the coefficients and the degrees of x and y. The tutorial then demonstrates the factoring process step-by-step, including how to undistribute the GCF from each term. Finally, it concludes with tips for performing these steps more efficiently in the future, emphasizing the use of the distributive property to verify the results.

What should you do if a term in the expression does not contain a variable present in other terms?

• Add a variable to the term.

• Do not factor that variable.

• Factor it out anyway.

• Ignore the term.
