\

Since the given equation $\"\"$ is a radical equation, once recheck the solution by back substitution.

\

$\"\"$

\

Substitute $\"\"$ in $\"\"$ .

\

$\"\"$

\

Since the above statement is false, $\"\"$ is not a solution of $\"\"$ .

\

$\"\"$

\

Substitute $\"\"$ in $\"\"$ .

\

$\"\"$

\

Since the above statement is true, $\"\"$ is a solution of $\"\"$ .

\

Thus, the solution is $\"\"$ .
