The given equation of the hyperbola is:
\[
4x^2 - 9y^2 - 24x - 36y - 36 = 0.
\]
Step 1: Convert the equation into standard form
Rearranging the equation:
\[
4x^2 - 9y^2 - 24x - 36y = 36.
\]
For the equation of the asymptotes, we remove the constant term:
\[
4x^2 - 9y^2 - 24x - 36y = 0.
\]
Step 2: Conclusion
Thus, the equation of the pair of asymptotes is:
\[
4x^2 - 9y^2 - 24x - 36y = 0.
\]
