- 5.3: Adding and Subtracting Polynomials
- Recall that we combine like terms, or terms with the same variable part, as a means to simplify expressions. To do this, add the coefficients of the terms to obtain a single term with the same variable part, but the variable part does not change. This, in addition to the commutative and associative properties of addition, allows us to add polynomials.
