**Problem Statement:**

Find an equation of the hyperbola that has vertices \((\pm \sqrt{5}, 0)\) and the length of the conjugate axis is 6.

**Equation:**  
\[ \frac{{\Box}}{1} \]

**Explanation:**

To find the equation of the hyperbola, we start with the standard form of a hyperbola centered at the origin:
\[
\frac{x^2}{a^2} - \frac{y^2}{b^2} = 1
\]

**Vertices and Axes:**

- The vertices \((\pm \sqrt{5}, 0)\) indicate that \(a = \sqrt{5}\).
- The length of the conjugate axis is 6, so \(2b = 6\) implying \(b = 3\).

Thus, the equation of the hyperbola becomes:
\[
\frac{x^2}{(\sqrt{5})^2} - \frac{y^2}{3^2} = 1
\]

By simplifying, we get:
\[
\frac{x^2}{5} - \frac{y^2}{9} = 1
\]
