Concept

Like Terms

Two or more terms in an algebraic expression are like terms if they have the same variable(s) with the same exponent(s).

7 x y + 2 x - 3 x y - 2 x^{2} + x + 5 x^{2}

In this expression, there are three sets of like terms — namely,

x y -

terms,

x -

terms, and

x^{2} -

terms.

Note that all constants are like terms. Like terms in an expression can be combined by using addition or subtraction to rewrite the expression in simplest form.
