Answer
$\dfrac{x}{3}; x \ne 2$
Work Step by Step
Factor the numerator and the denominator completely to obtain:
$=\dfrac{x(x-2)}{3(x-2)}$
Cancel the common factors to obtain:
$\require{cancel}
\\=\dfrac{x\cancel{(x-2)}}{3\cancel{(x-2)}}
\\=\dfrac{x}{3}; x \ne 2$
($x$ cannot be $2$ because it will make the original expression undefined.)
