we want to know what value/s of x cause the denominator to be 0. In order to determine the x value/s to be excluded from the domain, we must factor the denominator and set the factors = to 0
========================================================================
-9x^2 + 27x + 36 = (-9x+36)*(x+1)
=======================================================================
-9x+36=0
9x=36
x=4
========================================================================
x+1 = 0
x = -1
=====================================================================
Therefore, x = 4, x = -1 must be excluded from the domain
