Ok well lets just starrt solving for X.
Our equation is:
(x – 5)2 = 4
First we will distribute the 2 in this.

So...
(x – 5)2 = 4
will become..
2x-10=4
Then we will add the 10 to both sides.
2x-10=4
    +10+10
----------
2x=14

Next, we have to divide the 2 on both sides..
2x=14
2x/2=14/2
x=7

Now look at the choices given...  

 x = 3 and x = 11 

 x = 9 and x = 11 

 x = 9 and x = 1 

 x = 7 and x = 3 

There is only one answer choice with x=7.
Therefore the last answer choice is your answer.
