Please and thank you!

Answer 1

Solve for x,
x = ??
?p = ? then p = ?
the equation of the directrix is x= ?, then see neither it opens to the left or right.
then subs x that u already get is the equation of the directrix.
-------
for the first answerer,
h = ?
for the second answerer,
then Check your factoring. :) hope it help u..hehe :)
