Radical Inequalities |

Equations can contain variables under radicands. These are called radical inequalities. |
Below we have a radical inequality:
The value under the radical must be positive. First, we set the value of the radical greater than or equal to 0 to determine the minimum value of x:

Next, we solve for the inequality:

Any value of x between -3 and 118 is a valid solution to our inequality.
