3x + 5x = 8x   but   3x + 5y ≠ 8xy

Like terms are terms that have exactly the same variable part — the same letters raised to the same powers. Only the coefficients (the numbers in front) can differ.

For example, 3x² and −7x² are like terms because both have the variable part x². But 3x² and 3x are not like terms because the exponents differ.

Constants (plain numbers with no variable) are always like terms with each other.

When you combine like terms, you add or subtract the coefficients and keep the variable part unchanged.
Steps to Simplify
  • Write out every term in the expression, noting its sign.
  • Identify which terms share the same variable part (including exponent).
  • Group the like terms together.
  • Add (or subtract) the coefficients within each group.
  • Write the result for each group as a single term.
  • Arrange the simplified terms in a standard order (highest degree first).
