Answer:

C.The solution n = 0 is an extraneous solution.

Step-by-step explanation:

The given equation is \sqrt{n+4} =n-2.

Squaring both sides we have:

n+4=(n-2)^{2}

Expanding the right side:

n+4=n^{2} -4n+4

Or ,

n^{2} -5n=0

n(n-5)=0

n=0 or n=5.

Checking the solution for n=0 in the above equation:

\sqrt{0+4} =0-2 False .

For n=5.

\sqrt{5+4} =5-2

True.

C.The solution n = 0 is an extraneous solution.
