If xy = 5 and x^2 + y^2 = 10, then x/y + y/x = Choose the correct choice from the following:
A) 2
B) 3 1/7
C) 5 1/3
D) 7
E) 60
We can make simplifying of question and get it in view: (x^2 + y^2) / xy and as we know the meaning of this parts:   x^2 + y^2 = 10   xy = 5   we can calculate the answer 10/5 -&gt; 2 so answer is 2
