These answers are not really what usually comes out of the quadratic formula. You may have left something out. Do you mean %2810%2B-sqrt%2884%29%29%2F4???

If that is what you mean, then it would be

%2810%2B-sqrt%284%29%2Asqrt%2821%29%29%2F4
%2810+%2B-+2sqrt%2821%29%29%2F4
%282%285%2B-sqrt%2821%29%29%29%2F4
%285%2B-sqrt%2821%29%29%2F2

This is a longshot! I'm not sure what your problem was to begin with. If I did not understand correctly, why don't you re-post the problem, or send me an Email if you can wait until later today to get your problem solved.
