American ! and pisa says germany is bad !! :p

this was one question of my last math test :

2x³+3x²-23x-12=0
first u hav zo ty out which x1 must be so it is 0

x1 = 2 16+12-46-12 = NOT 0
x1 =4 128+16-92-12 = NOT 0
x1 = 3 54+27-69-12=0 RIGHT

so x1 = 3

now horner sheme :

--------2---3-----23 -12
---------6---27-------- 12
x1=3---2*3--9*3--4*3--0

2x²+9x+4=0

-> (now you could solve it foxtrot)

midnight formula :

x2/3 = -9+\- root:81-4*2*4/2*2

x2/3 = -9+\- root:49 /4

x2\3 = -9+\-7/4

x2 = -4

x3= -2/4 = -1/2

still easier than logarithm though ^^

Bleh, that's what graphing calculators are for :-P

x=4, x=-1/2, x=3

And boom, you're done... unless you want the imaginary answers too.. then you have to do a tad bit of work :-P

Here's the next question.

Two trains are heading towards each other on opposite tracks. Train A is traveling at 76 mph and Train B is traveling at 96 mph. In between the locations of the trains is a station. If the station is 18 miles away from Train B, then how much of a douchebag is George W. Bush?

Wow! Your intelligent and sophisticated form of amusing yourself impresses me. It must have taken you all night to think that one up. Wow..amazing...you're just a mini Einstein. :D You should be very proud of yourself.
