Understanding the Core Concept: What Are "Like Terms"?

Before we touch our specific expression, we must internalize the cornerstone principle: like terms. Also, this means they share the same variables raised to the same exponents. Like terms are terms that have exactly the same variable part. Their coefficients—the numerical factors—can be different, and that is precisely what allows us to combine them.

• Examples of Like Terms:
  • 5x and -2x are like terms (both have the variable x to the first power).
  • `
