When solving 3x^3+4x^2-7x+2 the rational zeros theorem says there can only be a possibility of zeros at plus minus 1, 2, 1/3, and 2/3
but for some reason a zero appears at about -2.4 (or more accurately -1-squareroot of 2).
How can this be? It states that if there are any zeros they will be listed by the theorem. It does not state the possibility of zeros lying outside that theorem.
