Ch 10: McDougal Littell Algebra 1 Chapter 10: Quadratic Equations & Functions

About This Chapter

The Quadratic Equations & Functions chapter of this McDougal Littell Algebra 1 Companion Course helps students learn the essential lessons associated with quadratic equations and functions. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Quadratic Equations & Functions textbook chapter.

How It Works:

  • Identify the lessons in the McDougal Littell Quadratic Equations & Functions chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the quadratic equations and functions topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn how to:

  • Define standard, vertex and intercept parabolas
  • Solve quadratics that aren't in standard form

9 Lessons in Chapter 10: McDougal Littell Algebra 1 Chapter 10: Quadratic Equations & Functions
What is a Parabola?

1. What is a Parabola?

A parabola is the U shape that we get when we graph a quadratic equation. We actually see parabolas all over the place in real life. In this lesson, learn where, and the correct vocab to use when talking about them.

Parabolas in Standard, Intercept, and Vertex Form

2. Parabolas in Standard, Intercept, and Vertex Form

By rearranging a quadratic equation, you can end up with an infinite number of ways to express the same thing. Learn about the three main forms of a quadratic and the pros and cons of each.

How to Solve Quadratics That Are Not in Standard Form

3. How to Solve Quadratics That Are Not in Standard Form

It isn't always the case that your equation will be set up nicely for you to solve. In this lesson, learn how to factor or use the quadratic formula to solve quadratic equations, even when they are not in standard form.

Solving Quadratic Equations with Square Roots or Graphing the Function

4. Solving Quadratic Equations with Square Roots or Graphing the Function

Quadratic equations can be solved in many ways, including taking square roots and graphing the function. In this lesson, learn how to use these techniques to solve quadratic equations.

How to Complete the Square

5. How to Complete the Square

Completing the square can help you learn where the maximum or minimum of a parabola is. If you're running a business and trying to make some money, it might be a good idea to know how to do this! Find out what I'm talking about here.

Completing the Square Practice Problems

6. Completing the Square Practice Problems

Completing the square is one of the most confusing things you'll be asked to do in an Algebra class. Once you get the general idea, it's best to get in there and actually do a few practice problems to make sure you understand the process. Do that here!

How to Use the Quadratic Formula to Solve a Quadratic Equation

7. How to Use the Quadratic Formula to Solve a Quadratic Equation

When solving a quadratic equation by factoring doesn't work, the quadratic formula is here to save the day. Learn what it is and how to use it in this lesson.

How to Solve Quadratics with Complex Numbers as the Solution

8. How to Solve Quadratics with Complex Numbers as the Solution

When you solve a quadratic equation with the quadratic formula and get a negative on the inside of the square root, what do you do? The short answer is that you use an imaginary number. For the longer, more helpful answer, check out this lesson!

Comparing Linear, Exponential & Quadratic Models

9. Comparing Linear, Exponential & Quadratic Models

This lesson will discuss how mathematical models are used to represent real world phenomena. We will look at linear, exponential, and quadratic models and their characteristics.
