$\lim_{ x \to 4 } { \left( \dfrac{ x ^{ 2 } -5x+4 }{ x ^{ 2 } -2x-8 } \right) }$
$\dfrac { 1 } { 2 }$
Find the limit value
$\lim\limits_{ x \to{ 4 } }{ \left( \color{#FF6800}{ \dfrac { x ^ { 2 } - 5 x + 4 } { x ^ { 2 } - 2 x - 8 } } \right) }$
$ $ Arrange the rational expression $ $
$\lim\limits_{ x \to{ 4 } }{ \left( \color{#FF6800}{ \dfrac { x - 1 } { x + 2 } } \right) }$
$\lim\limits_{ \color{#FF6800}{ x } \to{ \color{#FF6800}{ 4 } } }{ \left( \color{#FF6800}{ \dfrac { x - 1 } { x + 2 } } \right) }$
$ $ Substitute the value ​​in the limit expression $ $
$\color{#FF6800}{ \dfrac { 4 - 1 } { 4 + 2 } }$
$\color{#FF6800}{ \dfrac { 4 - 1 } { 4 + 2 } }$
$ $ Calculate the value $ $
$\color{#FF6800}{ \dfrac { 1 } { 2 } }$
