$\displaystyle 22x-\frac {8640}{x^2} -\frac {6220800}{x^4} = 0 $

$\displaystyle 22x = \frac {8640}{x^2} + \frac {6220800}{x^4} $

$\displaystyle 22x^5 = \frac {8640x^4}{x^2} + 6220800 $

$\displaystyle 22x^5 = 8640x^2 + 6220800 $

$\displaystyle 22x^5-8640x^2 = 6220800$ ...And this is where I am getting stuck.
