= \frac{256 x ^{64}}{128} + \frac{3072 x ^{56}}{128} + \frac{16128 x ^{48}}{128} + \frac{48384 x ^{40}}{128} + \frac{90720 x ^{32}}{128} + \frac{108864 x ^{24}}{128} + \frac{81648 x ^{16}}{128} + \frac{34992 x ^{8}}{128} + \frac{6561}{128}

\frac{256 x ^{64}}{128} = 2 x^{64}

\frac{3072 x ^{56}}{128} = 24 x^{56}

\frac{16128 x ^{48}}{128} = 126 x^{48}

\frac{48384 x ^{40}}{128} = 378 x^{40}

\frac{90720 x ^{32}}{128} = \frac{2835 x ^{32}}{4}

\frac{108864 x ^{24}}{128} = \frac{1701 x ^{24}}{2}

\frac{81648 x ^{16}}{128} = \frac{5103 x ^{16}}{8}

\frac{34992 x ^{8}}{128} = \frac{2187 x ^{8}}{8}

= 2 x^{64} + 24 x^{56} + 126 x^{48} + 378 x^{40} + \frac{2835 x ^{32}}{4} + \frac{1701 x ^{24}}{2} + \frac{5103 x ^{16}}{8} + \frac{2187 x ^{8}}{8} + \frac{6561}{128}
