Simplifying Expressions with Like Terms
7th Grade•45 minutes
Learning Objective
I can simplify algebraic expressions by combining like terms.
Key Concepts
Simplifying a polynomial involves identifying like terms that can be combined into a single term.
Like terms have the exact same variable part, which means the same letter raised to the same power.
To combine like terms, you add or subtract the number parts (coefficients) and keep the variable part the same.
