By inspection, you can see this will be a quadric. So aim to arrange your equation in the form:
AQ^2 + BQ + CQ = 0
Now see if it can be factored easily? Probably not worth a lot of effort on that so go straight to quadric solving equation.
This will give youTWO possible solutions of Q in terms of A,B,C
hint: multiplying everything by the same number does not change the solution for example 0.000006 * 1000000 = 6
