8x%5E%281%2F3%29-4x%5E%28-2%2F3%29
The smallest power of x is -2/3, so factor x%5E%28-2%2F3%29 out of both terms.

And both terms have a constant factor of 4, so factor that out also.

%284x%5E%28-2%2F3%29%29%282x-1%29

Then, since the instructions say to express the result using only positive exponents, move the negative exponent from the numerator to the denominator.

ANSWER: %284%282x-1%29%29%2F%28x%5E%282%2F3%29%29
