$\lim_{ x \to -2 } { \left( \dfrac{ 2x+4 }{ \sqrt{ x+11 } -3 } \right) }$
$12$
Find the limit value
$\lim\limits_{ \color{#FF6800}{ x } \to{ \color{#FF6800}{ - } \color{#FF6800}{ 2 } } }{ \left( \color{#FF6800}{ \dfrac { 2 x + 4 } { \sqrt{ x + 11 } - 3 } } \right) }$
$ $ Rationalize the numerator or denominator. $ $
$\color{#FF6800}{ 2 } \color{#FF6800}{ \times } \color{#FF6800}{ 6 }$
$\color{#FF6800}{ 2 } \color{#FF6800}{ \times } \color{#FF6800}{ 6 }$
$ $ Calculate the value $ $
$\color{#FF6800}{ 12 }$
