1. The problem statement, all variables and given/known data .002x - .000001x^2 = .50 2. Relevant equations -b+-sq.rt.((b^2)-(4ac))/2a 3. The attempt at a solution Plugging a=-.000001, b=.002, and c=-.5 does not get the the correct answer. x is supposed to be 292.89. I can't remember any other way of going about trying to get this answer. Any suggestions?
