1.1.4 Simplifying Algebraic Expressions (continued)
Example 3 Simplifying Expressions
Recall that the terms of an algebraic expression are separated by addition or subtraction symbols. Like terms have the same variables raised to the same exponents. Constant terms are like terms that always have the same value. To simplify an algebraic expression, combine the like terms by adding or subtracting their coefficients. Note that algebraic expressions are equivalent if they contain exactly the same terms when simplified.
