Enter any polynomial expression and this tool will combine all like terms, showing you exactly how each group is identified and simplified — step by step.
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.
