The vertex is at  (5,-4) and it is sideways so

 

\((y+4)^2=k(x-5) \)

 

It appears to pass through (3,-2)

sub

 

\((-2+4)^2=k(3-5)\\ 4=k*(-2)\\ k=-2\\ (y+4)^2=-2(x-5)\\\)

That is the formula

So the question does not make much sense

No, you cannot have the answer. I have already done the hard part.

If you cannot finish it then your teacher needs to know.

It means you are in the wrong class or she/he is teaching at an inappropriate level.

 

You rearrange it by expanding both sides separately.

And then take everything over to one side and put it equal 0.
