as a freshman you should be quite and try to listen to your math teacher. believe it or not he (or she) is pretty smart, probably smarter than you. show some respect, teachers are underpaid, under appreciated, and esential to society.

Yes, you have no understanding of complex numbers just because you can say j root (2).

If you really want to "be right", learn some more math, instead of parroting things you've picked up on internet forums. Sure as hell, if you tried it on with me in a maths class, I would ask you for a detailed explanation of your analysis.

the square root of any negative number is always going to be i. this is because there is no number which you can square to get a negative number, it will always be positive.

In retrospect, it was a stupid thing to do, and I wish we'd learned more math.

You need to use complex or imaginary number sets to take a - SqrRt .

i.this is because there is no number which you can square to get a negative number, it will always be positive.i.-2 = -1 x 2

so (root) -2 = (root) (-1 x 2),

which is (root) 2

i(ibeing (root) -1L
