Subtracting Polynomials Teacher Resources

Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication i.e. one can add, subtract, and multiply polynomials.

View this tutorial to see the steps needed in order to add polynomials vertically. [4:12]

Demonstrates how to add two given polynomials. One of the polynomials can be simplified before being added to the other polynomial. [2:10]

This video has a basic example of simplifying a polynomial expression with multiple variables.

Students practice adding polynomials with these exercises. They receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

In this lesson, students will be introduced to polynomials. A polynomial is a made up of terms, which are algebraic expressions combined by addition or subtraction. In a polynomial, there is no expressions that involve dividing by the...

An old video where Sal adds (5x^2+8x-3) + (2x^2 - 7x + 13x).

Proposing the concept that subtraction does not exist, it is merely adding the opposite, the Math Club parodies The Matrix and Batman. [5:41]

Demonstrates how to add polynomials using both the horizontal and vertical formats.

Use the examples and explanations on adding, subtracting, and multiplying polynomials to review the operations with polynomials.

This site, which is given by the University of Saskatchewan, provides a general overview of polynomials and roots. Examples and exercises are included.

This article gives an overview for adding, subtracting, multiplying, and dividing polynomials. Examples are given, but more importantly, they are accompanied with explanations of why the process worked.

This site gives a short interactive quiz which allows students to self-assess their understanding of the concept of adding polynomials.

Sal simplifies (5x^2 + 8x - 3) + (2x^2 - 7x + 13x).
