In this lesson, we learn how to solve quadratic equations by completing the square when the coefficient of x squared is not one. The teacher shows how to divide everything by the coefficient to get an equation with one x squared, then adds a number to both sides to make it a perfect square trinomial. Using the square root property, the teacher then shows how to solve for x and simplify the answer into two possible solutions.
