y%5E2%2B14y%2B49-49-119=24x completingthesquare
y%5E2%2B14y%2B49=24x%2B119%2B49
%28y%2B7%29%5E2=24x%2B168
highlight%2824%28x%2B7%29=%28y%2B7%29%5E2%29


This parabola has a horizontal symmetry axis and the vertex is the point at the left of the graph; and parabola opens to the right.

You should be able to figure the vertex, directrix, and focus on your own. You already have another example from other post worked through.
