I'd do it this way:
\starttext
\startitemize[n][style=\bf]
\item\vtop{%
\startitemize[a,horizontal,four][stopper=\)]
\startitem
$6(x - \dfrac{5}{12})^2 - \dfrac{1}{24}$
\stopitem
\startitem
$-3(x - \dfrac{1}{3})^2 + \dfrac{1}{3}$
\stopitem
\startitem
$7(x + \dfrac{5}{14})^2 + \dfrac{199}{28}$
\stopitem
\startitem
$-\dfrac{1}{2}(x + 2)^2 + \dfrac{9}{2}$
\stopitem
\stopitemize
}
\stopitemize
\stoptext
