Will my grandchildren ever have to remember the quadratic formula?

MSN Search Solves Equations: For those tackling math equations, MSN Search has a nice feature: it solves them. Try [((122.78+(x^2))/190)=.93] and the direct answer (as taken from MSN Encarta) will read:

((122.78+( x^2))/190)=.93 = x=7.343024 x=-7.343024

And that's a feature not even the Google Calculator has.

Now I can procrastinate by feeding it equations, hoping to find one that will break it...
