The domain of a rational function is the set of real numbers excluding any values that would make the denominator equal zero.  Take your denominator polynomial, set it equal to zero, and then solve.  (You&#39;ll need the quadratic formula on this one but the roots are real).  The domain is the set of real numbers excluding the two roots you just calculated.
