Lesson Summary:

This lesson covers the basics of factoring a polynomial by factoring out the greatest common factor. By understanding how to factor out the greatest common factor, students will be able to simplify polynomials and write them in their factored form. Through step-by-step examples, learners will see how to identify the greatest common factor, write it out in front of the polynomial, and then multiply it by what's left inside the parentheses to get back to the original polynomial.

Lesson Description:

This shows the basics of factoring a polynomial by factoring out the greatest common factor.
