Then let us square both sides
Subtract 2 from both sides to get the value of x
You have two choices with 14
Which one will you choose?
To answer this you must know does this value including the domain or not
Let us try this value for x in the equation if the left-hand side equals the right-hand-side then the value is not extraneous
