The "possible" integral zeros are:

Actually

#### Explanation:

Given:

#P(p) = p^4-2p^3-8p^2+3p-4#

By the rational roots theorem, any rational zeros of

That means that the only possible rational zeros (which also happen to be integers) are:

#+-1, +-2, +-4#

In practice we find that none of these are actually zeros, so
