Lesson Summary:

In this lesson, you will learn how to recognize and factor perfect square trinomials. Perfect square trinomials have the first and last term as perfect squares, and the middle term is even. With this knowledge, you can try trial factors more efficiently to find the right factorization. However, it is crucial to check your answer by multiplying it out. By following these steps, you can factor perfect square trinomials with ease.
