This is the standard form of the hyperbola.
The x-2 and y-3 are from the center point.
The first denominator is the distance from the center point to the vertex
The Sqrt(5) is a bit tougher to explain. A triangle is formed, a^2 + b^2 = c^2
A is that distance 2. C is the distance from center to Foci or 3. And B is the resulting Sqrt(5)
