Hi
{{{(x-2)^2/9 -(y-5)^2/ 4=1}}} Center(2,5) Vertices (-1,5) and (5,5)
See below descriptions of various conics
{{{drawing(300,300,  -10,10,-10,10, grid(1), 
circle(2, 5,0.3),
circle(-1, 5,0.3),
circle(5, 5,0.3),graph( 300, 300,-10,10,-10,10,0, 2*sqrt((x-2)^2/9 -1)+5,-2*sqrt((x-2)^2/9 -1)+5 ))}}}

Standard Form of an Equation of a Circle is {{{(x-h)^2 + (y-k)^2 = r^2}}} 
where Pt(h,k) is the center and r is the radius

 Standard Form of an Equation of an Ellipse is {{{(x-h)^2/a^2 + (y-k)^2/b^2 = 1 }}}
where Pt(h,k) is the center and a and b  are the respective vertices distances from center.

Standard Form of an Equation of an Hyperbola opening right andd left is:
  {{{(x-h)^2/a^2 - (y-k)^2/b^2 = 1}}} where Pt(h,k) is a center  with vertices 'a' units right and left of center.
Standard Form of an Equation of an Hyperbola opening up and down is:
  {{{(y-k)^2/b^2 - (x-h)^2/a^2 = 1}}} where Pt(h,k) is a center  with vertices 'b' units up and down from center.

Using the vertex form of a parabola opening up or down, {{{y=a(x-h)^2 +k}}}
 where(h,k) is the vertex
 The standard form is {{{(x -h)^2 = 4p(y -k)}}}, where  the focus is (h,k + p)
