Question 456793: List the possible rational zeros of: 3x^4+2x^3-x+15.
I know the answer from the back of the book but if
you could show the work so i could see how you did
it that would be nice. Thank you.

You can put this solution on YOUR website! List the possible rational zeros of: 3x^4+2x^3-x+15.
----
Rational roots have the form p/q.
---
p must be a divisor or 15: +-1,+-3,+-5,+-15
-----
q must be a divisor of 3: +-1,+-3
------
The possible forms of p/q = +-1,+-3,+-5,+-15,+-1/3,+-5/3
