I would like to know how to factor this expression x43x132x2

I would like to know how to factor this expression: x^4/3-x^1/3-2x^-2/3

x^4/3-x^1/3-2x^-2/3

Lets rewrite the expression:

x^4/3 - x^1/3 -2/x^2/3

Take x^2/3 as LCD:

{x^(4/3 +2/3) - x^(1/3 +2/3) -2}/x^2/3

(x^2 - x^1 - 2)/x^2/3

(x^2 -x -2)/x^2/3

factorise numerator : ( x^2 -2x +x -2)/x^2/3

(x+1)(x-2)/x^2/3
