$8 \sqrt{ 5 }$
Calculate the value
$\left ( \color{#FF6800}{ 2 } \color{#FF6800}{ + } \sqrt{ \color{#FF6800}{ 5 } } \right ) ^ { \color{#FF6800}{ 2 } } - \left ( 2 - \sqrt{ 5 } \right ) ^ { 2 }$
$ $ Calculate power $ $
$\color{#FF6800}{ 4 } \sqrt{ \color{#FF6800}{ 5 } } + \color{#FF6800}{ 9 } - \left ( 2 - \sqrt{ 5 } \right ) ^ { 2 }$
$4 \sqrt{ 5 } + 9 - \left ( \color{#FF6800}{ 2 } \color{#FF6800}{ - } \sqrt{ \color{#FF6800}{ 5 } } \right ) ^ { \color{#FF6800}{ 2 } }$
$ $ Calculate power $ $
$4 \sqrt{ 5 } + 9 - \left ( \color{#FF6800}{ - } \color{#FF6800}{ 4 } \sqrt{ \color{#FF6800}{ 5 } } \color{#FF6800}{ + } \color{#FF6800}{ 9 } \right )$
$4 \sqrt{ 5 } + 9 \color{#FF6800}{ - } \left ( \color{#FF6800}{ - } \color{#FF6800}{ 4 } \sqrt{ \color{#FF6800}{ 5 } } \color{#FF6800}{ + } \color{#FF6800}{ 9 } \right )$
$ $ Change the symbol of each term in parentheses when there is a (-) symbol in front of parentheses $ $
$4 \sqrt{ 5 } + 9 + \color{#FF6800}{ 4 } \sqrt{ \color{#FF6800}{ 5 } } \color{#FF6800}{ - } \color{#FF6800}{ 9 }$
$4 \sqrt{ 5 } \color{#FF6800}{ + } \color{#FF6800}{ 9 } + 4 \sqrt{ 5 } \color{#FF6800}{ - } \color{#FF6800}{ 9 }$
$ $ Remove the two numbers if the values are the same and the signs are different $ $
$4 \sqrt{ 5 } + 4 \sqrt{ 5 }$
$\color{#FF6800}{ 4 } \sqrt{ \color{#FF6800}{ 5 } } \color{#FF6800}{ + } \color{#FF6800}{ 4 } \sqrt{ \color{#FF6800}{ 5 } }$
$ $ Calculate between similar terms $ $
$\color{#FF6800}{ 8 } \sqrt{ \color{#FF6800}{ 5 } }$
