This is comprehensive lesson that considers many aspects of quadratic functions. It includes using factoring, completing the square and the use of the quadratic formula for finding the zeros of the function (including imaginary roots). It also reverses the whole process by looking at either different graphs of quadratic functions or zeros that are given and challenges the learner to derive the function. This lesson provides an excellent review for the second year algebra student or a multi-lesson unit for the more novice student.
This is a great introductory lesson plan to the quadratic formula. First, the formula is derived by completing the square. Then, it is used to solve some quadratric equations, and the discriminant is explored. Extra practice problems are included as are real-world application problems.
