Let be four integers such that is odd and is even,

then has

options::

(a) at least one irrational roots
(b) all three rational roots
(c) all three integral roots
(d) none of these

it cant have any irrational roots because then would be equal to an irrational number, and hence (a) is not correct and (b) is correct. (c) is a stupid answer since all of the integral roots would be rational as well
