give all possible rational zeros for the following polynomial p(x)=-2x4 2x3 5x2 18

you need to put pluses or minuses between the terms before I can solve it.

------------------------------------------------------------------------------------------------

Well, anyway, whatever the signs are we can use the roots test:

the factors of 18 are: 1,2,3,6,9,18

the factors of 2 are: 1, 2

So, the possible roots are

+/-1/2,+/-1,+/-3/2,+/-3,+/-6,+/-9/2,+/-9,+/-18

I meant the rational roots test
