None of the above...
Since there are pluses everywhere, you probably have pluses in both factors if there are two factors. Let's start with the simple deduction, that this is (x+a) squared. If it was, then a squared would be 169 and 2a would be 26. In fact that works perfectly, since 13 squared is 169.
so it is (x+13)(x+13)

Are you sure you got the right question to the answer?
Cause I got (x+13)^2
13*13= 169
13+13= 26
