RE: Coefficient problem


Hello !

You can proceed like this :

delta[poly2_, var_] := Coefficient[poly2, var, 1]^2 - 4*Coefficient[poly2,
var, 0]*Coefficient[poly2, var, 2]

Hi,

Now I'm trying to calculate this formula:

Delta[eq_, x_]:=Coefficient[eq, x]^2 - 4 Coefficient[eq, x^2]
Coefficient[eq, x^0]

eq has this form a x^2 + b x + c

But there is a problem with the x^0 coefficient!
How can I overcome that?

Thanks!

CeZaR
