What does a zero pair result in when simplifying polynomials?

• An x tile

• A 1 tile

• No change

• It cancels out the pair

Why do we not combine different types of terms when simplifying polynomials?

• Because they represent different quantities

• To make the polynomial longer

• Because it's easier to visualize
