Kirobaito: Wish it was that easy... Our teacher requires the solving, not the result
Flying Mullet,
Well, I tried that, but it doesn't seem to give any hints about how to solve it...(x<SUP>3</SUP> + 1)(x + 1)
which you can cut into:
(x<SUP>3</SUP> + 1)/x * (x + 1)/x = 4
This problem is supposed to turn out very easy once you find the way how to do it... At least, that's how other problems in that textbook worked.
rubah, I'm afraid graphing isn't an option

Edit: The answer is supposed to be: x1 = x2 = 1; x3,4 =(-3 ± √5)/2
