Chapter 2, Section 3: Simplifying Algebraic Expressions/Combining Like Terms.

1. Ms. Dewey-Hoffman, 2009 2-3: Simplifying Algebraic Expressions

2. IDing Parts of an Algebraic Expression Any thing separated by addition or subtraction is a TERM . A term that has NO variable is a CONSTANT . Any number that multiplies a variable is a COEFFICIENT . 7a 4a 3b 6 + + - 7a 4a 3b 6 + + - 7 a 4 a 3 b 6 + + -

3. Parts of an Algebraic Expression/ Combining Like Terms Terms that have identical variables and exponents are LIKE TERMS . To SIMPLIFY Expressions with Like Terms, add or subtract them. If there are NO Like Terms, then you cannot simplify any more. 7a 4a 3b 6 + + - 8c ² 4a -2c³ 9 + + +
