6.6.6 Lesson Summary

Algebra 16.6.6 Lesson Summary

Search for key terms or text.

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 a2+2ab+b2a2+2ab+b2 or a22ab+b2a22ab+b2.
  • 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 (a+b)2(a+b)2 or (ab)2(ab)2. 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 (a2b2)(a2b2). There are no binomial factors that multiply together to get a sum of squares, so a2+b2a2+b2 is prime.
    • 6.6.3: Self Check
    • 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:

  • 6.6.5: Practice
