Simply rearrange the equations for the required variable.

\n

No fraction can be divided by $0$, so we make sure our answers can't produce that result.

\n

When you have given your answer, look at your denominator.

\n

The value(s) that make the denominator $0$ are the value(s) you define as not included in the range.

\n

Remember for squared variables, there are two possible answers; the positive and negative.
