In this lesson, we will discuss how to add and subtract polynomials in algebra by solving example problems.
First, we learn how to identify like terms and learn how to combine like terms in an algebraic expression that involves polynomials. Next we simplify the expression by adding the coefficients of like terms. Finally, we solve numerous examples to give plenty of practice.
