6.4.7 Lesson Summary

In this lesson, you learned how to:

• Find the greatest common factor of two or more expressions.
• Factor the greatest common factor from a polynomial.
• Factor by grouping.

Here are the activities that helped you reach those goals:

• 6.4.1: Finding Factors
  • In this activity, you reviewed how to find the factors of a number, monomial, or group of terms. This is an important skill used in factoring polynomials later in the lesson.
• 6.4.2: Finding the GCF of Two or More Expressions
  • In this activity, you found all the factors of two or more expressions and used that list to find their greatest common factor.
  • 6.4.2: Self Check
  • 6.4.2: Additional Resources
• 6.4.3: Factoring the GCF from Polynomials
  • In this activity, you found the GCF of two or more expressions and then factored it out of those terms using the “reverse” of the Distributive Property.
  • 6.4.3: Self Check
  • 6.4.3: Additional Resources
• 6.4.4: Factoring Polynomials by Grouping
  • In this activity, you recognized terms in an expression that shared factors and grouped them together to factor the polynomial.
  • 6.4.4: Self Check
  • 6.4.4: Additional Resources
• 6.4.5: Can you Factor the Polynomial?
  • In this activity, you used everything you learned in the lesson to determine if polynomials can be factored.

After these activities, you completed the following practice:
