Staff Review
This lesson goes through two more example quadratic equation problems. These are solved by completing the square, just as in previous lessons, but now the leading coefficient is not 1. This is not much of a problem, however, as you just have to divide the equation by the leading coefficient to make it 1. All steps and work are shown and explained.
