1. Use the Rational Zero Test to determine all possible rational zeros
of the function and then find all the actual zeros of: .
For this problem, the only rational zeros are factors of 18: .
We're in luck . . . The first one works!
Hence, is a factor of
We find that: .
. . Therefore, the zeroes are: .
2. Find all the solutions to: .
Therefore, the solutions are: .
