Name: ___________________ Hour: ______
 Learning Target: I can combine like terms to simplify an algebraic expression.
Simplify each expression by combining like terms.
ex 1. 3a + 4a – 2a
ex 2. 2f2 + 4f + 7f + 6g
7a – 2a = 5a
2f2 + 11f + 6g
Hint: f2 and f are unlike terms, so they cannot be combined
just like f and g are unlike terms and cannot be combined
