See below for two solutions.

If you want to use the quotient rule , you can.

$d/dx(-2/(3x)) = -d/dx(2/(3x))$

$= -[((0)3x-2(3))/(3x)^2]$

$= -[(-6)/(9x^2)] = 6/(9x^2) = 2/(3x^2)$

Alternatively , you can rewrite the expression before differentiating.

$d/dx(-2/(3x)) = d/dx(-2/3x^-1)$

Now use the power and constant multiple rules.

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

Use whichever method you like.
