Now THAT would have made more sense, certainly.

How about this one:

If the equation -x^2 + 2(k+2)x - 9k = 0 has two imaginary roots, what are the values of k ?

The source of all knowledge, my trusty TI-89 says 288 as well.

I guess I'm an idiot. I was always taught that you do the math inside () first, then multiplication, then division. So fuck your 288.

The funny thing is, that there are 100 page threads on other forums debating the shit out of this question.

Fuck you all. I passed my college algebra with a B and still can't do imaginary numbers and shit. No more algebra on the weekend.
