In this lesson, you learned how to:
- Factor perfect square trinomials.
- Factor differences of squares.
Here are the activities that helped you reach those goals:
- 6.6.1: Identifying Perfect Square Trinomials
- In this activity, you learned how to recognize perfect square trinomials. They always follow a pattern of or .
- 6.6.2: Factoring Perfect Square Trinomials
- In this activity, you learned how to factor perfect square trinomials. You can recognize that they will always factor to a form of or . In some cases, you first need to factor the GCF out of the existing terms.
- 6.6.2: Self Check
- 6.6.2: Additional Resources
- 6.6.3: Factoring the Difference of Squares
- In this activity, you learned how to factor using the difference of squares. In these problems, the middle term will always cancel to the form of . There are no binomial factors that multiply together to get a sum of squares, so is prime.

- 6.6.3: Additional Resources
- 6.6.4: Sorting Polynomials by Factoring Methods
- In this activity, you practiced recognizing which of these two methods you would use to factor based on the polynomial you were given. You learned that it is possible to have a polynomial that requires both of these methods to be factored completely.
After these activities, you completed the following practice:
