How to Add, Subtract and Multiply Polynomials

1. How to Add, Subtract and Multiply Polynomials

Adding, subtracting and multiplying polynomials are, basically, the same as adding, subtracting and multiplying numbers. They only difference is that we have a pesky variable to worry about, but this video will show you that's no problem, so no worries! This method has worked for many of my students, and I think it will work for you, too!

Operations with Polynomials in Several Variables

2. Operations with Polynomials in Several Variables

In this video lesson, you will learn how to handle and work with polynomials that have more than one variable. This is important because in math you sometimes have to work with several variables at the same time.

Using Rational & Complex Zeros to Write Polynomial Equations

3. Using Rational & Complex Zeros to Write Polynomial Equations

In this lesson, you will learn how to write a polynomial function from its given zeros. You will learn how to follow a process that converts zeros into factors and then factors into polynomial functions.

Forming Polynomial Equations with Roots

4. Forming Polynomial Equations with Roots

In this lesson you'll learn how to form polynomial equations when given the roots of the equation and look at some examples. Sample problems will include those involving multiple roots and squares.

Polynomial Inequalities: Definition & Examples

5. Polynomial Inequalities: Definition & Examples

Polynomial inequalities show up in real world applications when intervals of numbers are involved. In this lesson, you'll learn what polynomial inequalities are and how to work with them.

Terminology of Polynomial Functions

6. Terminology of Polynomial Functions

After watching this video lesson, you will be able to understand and use the words associated with polynomial functions like a pro. You will see words, such as leading coefficient, and you will immediately know what it is referring to.

Analyzing Graphs of Polynomial Functions

7. Analyzing Graphs of Polynomial Functions

This lesson will explain the graph of a polynomial function by identifying properties including end behavior, real and non-real zeros, odd and even degree, and relative maxima or minima. We will then sketch a graph using this information.
