Lesson 1: Connecting Zeros, Roots & x-intercepts
An interesting look at what functions are, and how they can be represented in real life.Lesson 5: Completing The Square
An excellent example of how you can use the 'completing the square' method to solve for an unknown constant (c) in a perfect square trinomial. Highly recommended!Another good example demonstrating how to use 'completing the square' to find the roots, or zeros, of a quadratic equation.
An excellent example where you must convert a quadratic equation into vertex (or standard) form, and identify the vertex. *Highly recommended!*
Lesson 6: The Quadratic Formula
First is a very helpful video that proves the quadratic formula.A quick and simple example of how to use the quadratic formula to solve a quadratic equation.
Lesson 7: The Discriminant
This gives an excellent description of what a discriminant is, and how it helps you identify the number of solutions to a quadratic equation. There are also a couple of examples. *Highly recommended.A great example that asks to find the number of possible solutions to a quadratic equation. *Highly recommended!*
Lesson 8: Applications - A Graphical Approach
This is a perfect example, nearly identical to page 348 in your workbook. Highly recommended!Lesson 9: Applications - An Algebraic Approach
This is another example that is nearly identical to one in your workbook (pages 347 and 355). *Highly recommended.A good example where knowing how to find the vertex of a quadratic equation can help you solve a problem.
