\[\huge x^4-4x^3+ax^2+bx+1 \]

Have you tried synthetic division?

but there are 3 variables .. :S

Yeah but you know a lot of algebra to deal with them.

Hmmm, I'm not exactly sure what the trick for this is.

\[
\large
x^4-4x^3+ax^2+bx+1=(x-1)(cx^3+dx^2+ex+f)+7
\]

@ burhan101
use factor and remainder theorem

when f(x) is divided by (x-a) the remainder is given by f(a)

thus
a+b=9
and a-b -3
thus solving above two eq
we have a=3 and b=6
