Polynomials chiefly consist of three terms: the constant, an exponent, and a variable. When adding polynomials, we just add like terms. The first thing to do is to identify the terms and then you just add them together. When you have more than two like terms it is helpful to create columns to work off of. When you are subtracting polynomials start by reversing the sign of each term and then add them as usual.
How to Add and Subtract Polynomials - Performing addition and subtraction operations on polynomials are just like combining like terms wit some order of operations. All you have to do is be careful of the subtraction signs and you're good to go. In this case, the PEMDAS approach will be considered, but for now, let's take simpler problems. For instance, you have to simplify (2x + 5y) + (3x - 2y). In this scenario, you cannot solve x and y terms, and you can only solve x and x terms and similarly with y terms. 2x + 5y + 3x - 2y, 2x + 3x + 5y - 2y, 5x + 3y. These worksheets explain how to add and subtract polynomial equations by combining like terms. Note: Answers will be in the form of a simplified polynomial equation.
