-b +- sqrt (b**2 -4ac)
X = --------------------------------------------

This makes at least two forums this question is posted on. I expect the count to rise as I check other forums.

I fully agree! We cannot do your homework for you, but we can help you if you get stuck. You have to do the coding legwork though.

He's forum shopping for the answer, posting the same question on multi-forums (up to three now that I have seen). I recommend you delete this thread, this person does not want help, he wants the answer coded and ready to turn in for a grade.
