Algebra- is my answer right

posted by .

Use the rational zeros theorem to list all possible rational zeros of the following.
-2x^3-x^2-4x-5
I got +-1,+-5+-,5/2,+-1/2
Be sure that no value in your list appears more than once.

    Yes, you have applied the theorem correctly. Not all of those possibilites are actual solutions, however. The only rational real solution is -1.
