Ferrari's method

[sunmilee]

Hi,
need to solve x^(4)-3x^(3)+3x^(2)-3x+2=0 in Ferrari's method of biquadratic formula.
Can somebody suggest a way to solve it easily?
Thanks,

Are you required to use Ferrari's method or you're just mentioning the source of the problem?
Personally, I would use the Rational Root Theorem.

... but this one is divisible by [imath]x-1[/imath], isn't it

I suppose the "inquisitor"s wanted lessen their pain of grading - thus provided easily "factorable" function.
