Solving an equation containing a radical

In like our next like example, like we are like going to like solve a radical equation.  Oh, sorry about that.  Let's try that again. In our next example, we are going to solve an equation that contains a radical.  No matter what we do, we must always try to isolate the radical before we start to solve the equation.  Once the radical is isolated, we can square both sides of our equation.  Solve the resulting equation whether it is a simple linear equation or a quadratic equation.
