<PRE><B>Question 886917</B>
Find all the zeros of P(x)=2x^3 - x^2 - 15x +18. 
Use the rational roots theorem:
With synthetic division

....0...|....2......-1.......-15.....18
....1...|....2.......1.......-14......4
....2.. |....2.......3.......-9........0 (2 is a root)
(x-2)(2x^2-3x-9)=0
(x-2)(x+3)(2x-3)=0
zeros are: -3, 3/2, 2
