Question 778259
No.  It still is RATIONAL.  You can multiply numerator and denominator by {{{x^2}}} and the resulting expression will then be a rational expression having no negative exponents in numerator nor denominator.  You should try the process and see yourself.


You need to be aware, that if you perform that process on your example expression, you must give yourself the restriction, x<>0, BECAUSE this is a necessary restriction in the originally given example.
