x=144

Explanation:

If we consider that in order to isolate and solve for an unknown value, whatever we do to one side we must do to the other:

Therefore, if we consider the equation;
x=12
In order to eliminate the square root of x and simply express the equation in terms of x, we must square both sides - remembering that whatever we do to onside of the equation we must do to the other to maintain the equality of the equation.
