Add 
to both sides:
Square both sides:
\ -\ 2\sqrt{x\ -\ 6}\ +\ 1)
Add 
to both sides:
Multiply both sides by 
Square both sides:
Standard form:
Solve the factorable quadratic. Check both roots in the original equation. ALWAYS check your solutions against the original equation when raising both sides to a power is a step in your solution. Raising both sides of an equation to a power often introduces extraneous roots. That is not necessarily the case here, but you MUST check for the situation.
