List all possibles zeros of the following polynomial expressions (Use P/Q): (Show Work)
a) x^3-2x^2+12x-18
P must be a factor of -18
Q must be a factor of 1
------
p:: +-1,+-2,+-3,+-6,+-9,+-18
Q:: +-1
-----
P/Q:: +-1 +-2,+-3,+-6,+-9,+-18
----------
b) x^4+5x^3-2x+21
P:: +-1,+-3,+-7,+-21
Q:: +-1
-----
P/Q: +-1,+-3,+-7,+-21
