Way back in the day someone showed me a quick way of getting the complex values of a quadratic eqatution using the sum and product of the roots.
Does anyone know it? i cannot for the life of me find it on line. I know how to find the sum and product of the roots, jst no idea how to relate it to a quadratic.
heres a quadratic with complex roots so you dont have to find one.... PM me or post up if u know the trick.
x^2+2r+4=0
Jesus man-that was about 12 years ago. My head hurts.
Don't you just use the quadratic equation to solve?

12 years ago i didnt even hit puberty yet. damn im young!
you can, but using quadratic is a lengthy process. compared to the short cut.
its someting like
r1-r2 = -b/a, and r1 x r2 = something that relates to -b/a so you're complex root is ____.
Man... just google it and use one of the solvers... that makes it really easy. ;D

Of course... it's cheating though... right?
it aint cheating if you're doing it right!
nah, but i need to know how to do this on a test, and quadratic is just really freaking time consuming and annoying.

It's a simple equation. Move faster, man.
Dude you know better than posting this crap on a motorcycle forum. Your could give some of the older guys a stroke or something.

put into TI-89, it will tell you all the roots, graph it, and make toast.
I never did like Algebra or Trig.
It might have been something learned in Geometry but for me all the stuff was like Greek and I swore I'd never do anything that required the use of such knowledge , so it was all purged from my brain to make room for more interesting stuff.

algebra is arabic, and therefore the product of terrorism.

x = boobies
Then would X
2 = 2 boobies? No that would be 2x = 2 boobies. Probably for the best because I doubt square boobies would be that attractive anyway.
has anyone ever seen the math equation to prove women are evil? thats some funny hsit
