# Math Help - Economics calculus problem.

1. ## Quadratic equation problem.

Don't know if this is the right forum to post this in but I'll give it a shot.

I'm trying to work out this economics math problem and I'm having trouble getting started.

Find the equation:

The breakeven outputs for profit are Q=2 and Q=12 (Roots).
Maximum profit is \$210. (Max/Vertex).

Thanks for any help!
