Answer:
is an extraneous solution.
Step-by-step explanation:
Given : Equation 
To find : Solve for x and identify if it is an extraneous solution?
Solution :
Step 1 - Write the equation,

Step 2 - Add 3 both sides,


Step 3 - Squaring both sides,


Step 4 - Divide both side by 16,


For extraneous solution, Substitute the value of x back in the equation.




The value of x does not satisfy the equation which means the value of x is an extraneous solution.
So,
is an extraneous solution.
