Get an inverted quadratic equation ([itex]-x^2[/itex]) with maximum y=100 and roots x=0 and x=1/120.

2. Relevant equations

3. The attempt at a solution

I tried changing the several terms of the quadratic equation, used the quadratic formula setting c=100, and x=0 with the negative root and x=1/120 with the positive root, among other less smart attempts. Could not get something reasonable.

Does anyone know how to do it? It does not seam that much difficult, maybe my academic formation is just weak.. =\
