Not quite, you're close.
:
%2818x%5E4%29%2F%2821x%5E2%29
Reduce the numerical portion of the fraction, divide numerator & denominator by 3
%286x%5E4%29%2F%287x%5E2%29
The variable, divide the one with lowest exponent into the one with higher
When you divide you subtract exponents so you have
%286x%5E%284-2%29%29%2F%287%29 = %286x%5E2%29%2F%287%29
