Hi guys, I was doing some stuff and found a constant which might simplify a deficit formula but I can't find a way to express it. I know it must be cubic but that's pretty much all I've figured out.

Are you doing finance or something. Tell me the problem, I'm good at making models.

A 4,000000E+00
B -7,200000E+01
C 3,240000E+02
thats a polynom of 2nd grade or whatever this is called in english i dont care
the differences scheme youre using is similar to a derivative in discrete form.
that your 2nd differences are constant should have told you somthing.

We say that the polynomial is of order two (2).

So [ax^2+bx+c]'' = [2ax+b]' = 2a = 8
a = 4
c = 324
4 + b + 324 = 256 => b = -72
You're welcome
