$( x -2 )^2/ 2^2 - (y +3)^2/3^2 = 1$ , equation of a hyperbola .

$9 x^2 -4 y^2 -36 x -24 y -36=0$ or

$9( x^2 -4 x ) -4 (y^2 +6 y) = 36$ or

$9( x^2 -4 x +4 ) -4 (y^2 +6 y +9) = 36$ or

$9( x -2 )^2 - 4 (y +3)^2 = 36$ or

$(9( x -2 )^2)/36 - (4 (y +3)^2)/36 = 1$ or

$( x -2 )^2/4 - (y +3)^2/9 = 1$ or

$( x -2 )^2/ 2^2 - (y +3)^2/3^2 = 1$

This is standard form of the equation of a hyperbola with center

at $( 2,-3)$
