= \frac{x ^{27}}{x ^{18}} - \frac{18 x ^{24}}{x ^{18}} + \frac{144 x ^{21}}{x ^{18}} - \frac{672 x ^{18}}{x ^{18}} + \frac{2016 x ^{15}}{x ^{18}} - \frac{4032 x ^{12}}{x ^{18}} + \frac{5376 x ^{9}}{x ^{18}} - \frac{4608 x ^{6}}{x ^{18}} + \frac{2304 x ^{3}}{x ^{18}} - \frac{512}{x ^{18}}

\frac{x ^{27}}{x ^{18}} = x^{9}

\frac{18 x ^{24}}{x ^{18}} = 18 x^{6}

\frac{144 x ^{21}}{x ^{18}} = 144 x^{3}

\frac{672 x ^{18}}{x ^{18}} = 672

\frac{2016 x ^{15}}{x ^{18}} = \frac{2016}{x ^{3}}

\frac{4032 x ^{12}}{x ^{18}} = \frac{4032}{x ^{6}}

\frac{5376 x ^{9}}{x ^{18}} = \frac{5376}{x ^{9}}

\frac{4608 x ^{6}}{x ^{18}} = \frac{4608}{x ^{12}}

\frac{2304 x ^{3}}{x ^{18}} = \frac{2304}{x ^{15}}

= x^{9} - 18 x^{6} + 144 x^{3} - 672 + \frac{2016}{x ^{3}} - \frac{4032}{x ^{6}} + \frac{5376}{x ^{9}} - \frac{4608}{x ^{12}} + \frac{2304}{x ^{15}} - \frac{512}{x ^{18}}
