In this lesson I will be teaching you the completing the square method of solving quadratic equations. First let me give you some good news and bad news about this method. Let’s start with the bad news- this method is very long and requires a good amount of work. The good news is once you get the skill down we never really use the completing square method as the method has a great short cut- it’s called the quadratic formula! Nevertheless it’s an important method to study and learn as it will put your equation solving skills to the test. As the name implies the method has to do with “square” roots. Basically we will be rewriting quadratic equations such that we can solve them by taking the square root of both sides. You need to take your time with these problems and having excellent notes is a must.
