Fast Math - Random Quadratic Equations

Really nice idea!

But pay attention to the signs, they're wrong more often than not.

it's a shame there's no way to require the taker to get the right signs - typing positive integers always gives it to you. oh well, fun quiz nonetheless, challenging to do under time pressure but not complaining

It's easy once you know how to factorize

Good job! Too bad signs don't work.
