Sometimes zero pairs must be added to close the rectangle. Adding zero pairs does not change the value of the original expression since they, like their name implies, equate to 0. For example, if you need to add an x tile, you MUST also add a -x tile to keep the balance of the expression. Factor
with algebra tiles.
