Like terms The like terms in this expression are the terms that can be grouped together by having exactly the same set of unknown factors. Here, the sets of unknown factors are formula_15 formula_16 and formula_17. By the rule in the first example, all terms with the same set of unknown factors, that is, all like terms, may be combined by adding or subtracting their coefficients, while maintaining the unknown factors. Thus, the expression becomes formula_18 The expression is considered simplified when all like terms have been combined, and all terms present are unlike. In this case, all terms now have different
