The answer is the last option (Option D), which is:
 D. 25
 The explanation is shown below:
 1. You have that:
 (a ± b)^2=a^2 <span>± 2ab + b^2
 2. The expression given in the problem is:
 </span><span>x^2-10x+n
 Where x^2=a and 2ab=10x
 2b=10
 b=10/2
 b=5
 3. Therefore, you have:
 b^2=5
 b^2=25
 b^2=n
 n=25</span>
