Combining Like Terms

What does it mean to combine like terms in an expression?

• To simplify an expression by adding or subtracting terms that have the same variable raised to the same power.

• To multiply different terms in an expression together.

• To separate terms in an expression into different groups.

• To change the variables in an expression to different values.

How do you identify like terms in an expression?

• By looking for terms that have the same variable and exponent.

• By checking if the terms have the same coefficient.

• By identifying terms that are both positive or both negative.

• By counting the number of terms in the expression.

What happens if you try to combine unlike terms?

• You can combine them into a single term.

• They remain separate in the expression.

• They become equal to each other.

• You can only combine them if they have the same coefficient.

What is the first step in simplifying an expression with like terms?

• Group the like terms together.

• Multiply the terms by their coefficients.

• Add the constants separately.

• Distribute the terms across the expression.
