Lesson Summary:

In Completing the Square 1, we learn how to add a constant or a variable term to a binomial to make a perfect square trinomial, and then how to write that perfect square trinomial in factored form. Through various examples, the instructor shows how to complete the square to write perfect square trinomials and how to identify what needs to be added to make a perfect square. By the end of the lesson, you'll have a solid understanding of how to use this technique to solve quadratic equations.
