$4$
Find the limit value
$\lim\limits_{ x \to{ 2 } }{ \left( \color{#FF6800}{ \dfrac { x ^ { 2 } - 4 } { x - 2 } } \right) }$
 Arrange the rational expression 
$\lim\limits_{ x \to{ 2 } }{ \left( \color{#FF6800}{ x } \color{#FF6800}{ + } \color{#FF6800}{ 2 } \right) }$
$\lim\limits_{ \color{#FF6800}{ x } \to{ \color{#FF6800}{ 2 } } }{ \left( \color{#FF6800}{ x } \color{#FF6800}{ + } \color{#FF6800}{ 2 } \right) }$
 The limit of a polynomial approaching a real value is equal to the polynomial substituting that number
