Combine Like Terms

What are polynomials?

• Chains of terms that are multiplied together.

• Chains of terms that are either added or subtracted together.

• Single terms with a number part and a variable part.

• Expressions that only contain numbers.

What is the primary purpose of simplifying polynomials?

• To make them more complicated.

• To identify missing terms.

• To make them shorter and easier to work with.

• To change their degree.

When combining like terms, what operation is performed on their number parts?

• They are multiplied.

• They are divided.

• They are added or subtracted.

• They are ignored.

What characteristic must terms share to be considered "like terms"?

• They must have the same number part.

• They must have different variable parts.

• They must have exactly the same variable part.

• They must be adjacent in the polynomial.
