Answer
The constant term is a multiple of 3,
The leading coefficient is a multiple of 4.
Work Step by Step
By the Rational Zero Theorem,
if there is a rational root$, \displaystyle \frac{p}{q}$, of a polynomial equation,
then p is a factor of the constant term, $a_{o}$ and
q is a factor of the coefficient of the leading term $a_{n}$.
--------------------
$\displaystyle \frac{p}{q}=\frac{3}{4}$ is a root.
3 is a factor of the constant term,
4 is a factor of the leading term.
Or,
The constant term is a multiple of 3,
The leading coefficient is a multiple of 4.
