A restricted value is a value that will make the fraction undefined, and thus will make it impossible to exist.

Restricted values can exist in two forms: asymptotes and holes.

By simplifying all sides of this expression, we can find the restricted values.

After finding factors, and then cancelling like factors, keeping in mind the original factors in the denominator, we can find three restrictions:

1, 2, and - 2.
