Identify the conic section $$$- 72 x y = -5$$$

Identify and find the properties of the conic section $$$- 72 x y = -5$$$.

The general equation of a conic section is $$$A x^{2} + B x y + C y^{2} + D x + E y + F = 0$$$.

In our case, $$$A = 0$$$, $$$B = 72$$$, $$$C = 0$$$, $$$D = 0$$$, $$$E = 0$$$, $$$F = -5$$$.

The discriminant of the conic section is $$$\Delta = 4 A C F - A E^{2} - B^{2} F + B D E - C D^{2} = 25920$$$.

Next, $$$B^{2} - 4 A C = 5184$$$.

Since $$$B^{2} - 4 A C \gt 0$$$, the equation represents a hyperbola.

To find its properties, use the hyperbola calculator.

$$$- 72 x y = -5$$$A represents a hyperbola.

General form: $$$72 x y - 5 = 0$$$A.
