    http://www.wolframalpha.com/input/?i=+f%28x%29%3D50x%2F%28x%5E2%2B3%29 it says max is at x = sqrt(3)

    the explanation goes: where the first derivative is zero you have a min or a max; so test out the points. but if you dont know the derivatives thats a little beyond the scope of this environment
