ANSWER

The possible rational zeros are,



EXPLANATION

According to the rational roots theorem, the possible rational zeros of the polynomial



are all the possible factors of the constant term

expressed over all the possible factors of the highest degree of the polynomial which is 1 in the simplest form.

Therefore the possible rational zeros of the given polynomial function are,
