The polynomial equation $x^3 - ax^2 + bx - c = 0$, where $a$, $b$, and $c$ are integers, and it has $6$ as on of its roots. According to the rational root theorem, what is the value of $c$?
The answer is $18$, but I'm struggling with how to get there. Can someone show me the steps to solve this? I'm trying to use the Rational Root Theorem but doing it in a reverse order? Confused.
