Find the solution of the square root of the quantity of x plus 2 plus 4 equals 8, and determine if it is an extraneous solution

Consider the equation:

Subtracting '4' from both the sides of the equation, we get as

Squaring on both the sides of the equation, we get

Subtracting '2' from both the sides of the equation, we get

x=14

Since, An extraneous solution is a solution that arises from the solving process that is not really a solution at all. But, in this equation x=14 is the solution of the given equation.

Hence, it is not an extraneous solution.

i believe the answer is c.
