\

$\"\"$ (Square on each side)

\

$\"\"$ (Cancel square root)

\

$\"\"$ (Evaluate power $\"\"$ )

\

$\"\"$ (Subtract $\"\"$ from each side)

\

$\"\"$ (Apply additive inverse property: $\"\"$ )

\

$\"\"$ (Subtract: $\"\"$ )

\

$\"\"$ (Divide each side by $\"\"$ )

\

$\"\"$ (Cancel common terms)

\

Therefore, the value of $\"\"$ is $\"\"$ .
