list all the potential rational zeros of 3x^4 + -5x^3 + 3x^2 - 7x + 2
Ok so i know that p = 2 so then you would have +/-1, and +/-2. Then the q = 3 so then you would +/- 1 and +/-3. Then my possible rational zeros would be +/- 1, +/- 2, +/- 1/3, and +/- 2/3. Then you plug in thos numbers till you get a remainder of zero using synthetic division. I did this but none of these gave me a remainder of zero. Someone please help me.
