Powered by Interact. In order to add or subtract polynomials, it's important to understand like terms first. Like terms are terms that have the exact same variable part, they must have the same variables raised to the same powers. Like terms can have a different coefficient the number in front of the variable , but the variable parts must match exactly. You can only combine terms together if they are like terms. If they aren't like terms, you have to keep them separate.

Simplifying rational expressions combines everything learned about factoring common factors and polynomials. When simplifying rational functions , factor the numerator and denominator into terms multiplying each other and look for equivalents of one something divided by itself. Adding and subtracting polynomials is really just a fancy way of combining like terms, one thing you have to be careful with subtracting though of course is remembering that the minus sign applies to every term every polynomial. But first let's look at some different ways you can organize your work for adding and subtracting polynomials.

## How to Add and Subtract Polynomials

As you will see below, in order to add or subtract polynomials , you really just need to pay attention to signs and combine like terms., Subtracting Polynomials is very similar to adding polynomials. We can add and subtract polynomials by combining like terms, which are terms that contain the same variables raised to the same exponents. We can check our answers to these types of problems using a graphing calculator. -
