Help algebra.com: Addition and Subtraction of Polynomials

Though they " sound like a really fancy word," polynomials prove to be no match for Sal's mathematical skills. After defining the term and providing a few examples, Sal works through a few equations that add or subtract polynomials,...

Beginning a "handful of fairly simple inequality videos," Sal demonstrates a few inequality problems in which mathematicians need to add or subtract. Though he states that his goal is to familiarize viewers with the notation, his...

A rational expression is a fraction where the denominator and/or the numerator is a polynomial. The resource presents rational expressions and how to add and subtract them. Additionally, the video connects the addition and subtraction of...

[Free Registration/Login may be required to access all resource tools.] Here you'll learn how to add and subtract polynomials, as well as learn about the different parts of a polynomial. Practice problems are also included.

Stack the like terms to add vertically. The resource contains a visual aid to help with the addition of polynomials using the vertical method. Pupils use the aid to calculate the sum of two polynomials.

[Free Registration/Login may be required to access all resource tools.] In this lesson students learn to add and subtract polynomials. Students can watch a video tutorial, explore guided notes and attempt practice problems.

Slide the coefficients to determine sums of polynomials. The interactive contains sliders to change the coefficients of an addend in a polynomial addition problem. Pupils determine the coefficients of the addend to arrive at particular...

Video defines what a polynomial is, identifies some different types of polynomials, explains how to determine the degree of a polynomial, shows how to add and subtract polynomials, and shows how to write polynomial expressions to...

Finding the additive inverse is not as complicated as you might think. The instructor demonstrates how to multiply each of the terms in the polynomial by -1 and explains how this works. But wait, there's a quicker way. What's that you...

The teacher explains the many steps in simplifying a rational expression using opposite binomial factors. At first it seems complicated but if you follow along and watch out for your negative numbers you can learn how to simplify this...
