The value of displaystyle lim x arrow ∞((x2/3 x-2)-(x/3)) is = displaystyle lim x arrow ∞ (3 x2-3 x2+2 x/(3 x-2) 3) = displaystyle lim x arrow ∞ (2 x/3(3 x-2)) = displaystyle lim x arrow ∞ (2/3(3-(2)x))=(2/9)

Q. $x \to \infty lim (\frac{x ^{2}}{3 x - 2} - \frac{x}{3}) =$

$\frac{1}{3}$

$\frac{2}{3}$

$\frac{- 2}{3}$

$\frac{2}{9}$

The value of $x \to \infty lim (\frac{x ^{2}}{3 x - 2} - \frac{x}{3})$ is
$= x \to \infty lim \frac{3 x ^{2} - 3 x ^{2} + 2 x}{( 3 x - 2 ) 3}$
$= x \to \infty lim \frac{2 x}{3 ( 3 x - 2 )}$
$= x \to \infty lim \frac{2}{3 ( 3 - \frac{2}{x} )} = \frac{2}{9}$
