Mathematics - 5 August 2007

Does anyone know where I can get a TI-84 Plus Silver Graphing Calculator for cheaper than they are in the stores ( about $117.00). I need one for math class and I don't really want to pay 117 dollars. Thanks in Advance!

I think this is interesting:

Let P be a polynomial with integer coefficients, such that the coefficients of the leading and of the independent terms are odd and the total number of odd coefficients is odd. Like in P(x) = x^3 + 5x^2 -2x - 1. Show that P has no root with both real and imaginary parts rational.

x^2 - 4.5 x -100=0

how to solve it for roots ?

my concern is ....coefficient is 4.5 ......fraction ....so i face difficulty in factoring .

I cant use direct formula x= -b+/ sqrt(b^2-4ac)/2a ..........because its becoming messy .

can anybody suggest some smarter way to solve it ?
