$6 - 7 i$
Calculate the value
$\left ( 4 - 2 i \right ) \color{#FF6800}{ - } \left ( \color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ + } \color{#FF6800}{ 5 } \color{#FF6800}{ i } \right )$
$ $ Change the symbol of each term in parentheses when there is a (-) symbol in front of parentheses $ $
$\left ( 4 - 2 i \right ) + \color{#FF6800}{ 2 } \color{#FF6800}{ - } \color{#FF6800}{ 5 } \color{#FF6800}{ i }$
$\left ( \color{#FF6800}{ 4 } \color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ i } \right ) \color{#FF6800}{ + } \color{#FF6800}{ 2 } \color{#FF6800}{ - } \color{#FF6800}{ 5 } \color{#FF6800}{ i }$
$ $ Get rid of unnecessary parentheses $ $
$\color{#FF6800}{ 4 } \color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ i } \color{#FF6800}{ + } \color{#FF6800}{ 2 } \color{#FF6800}{ - } \color{#FF6800}{ 5 } \color{#FF6800}{ i }$
$\color{#FF6800}{ 4 } - 2 i \color{#FF6800}{ + } \color{#FF6800}{ 2 } - 5 i$
$ $ Add $ 4 $ and $ 2$
$\color{#FF6800}{ 6 } - 2 i - 5 i$
$6 \color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ i } \color{#FF6800}{ - } \color{#FF6800}{ 5 } \color{#FF6800}{ i }$
$ $ Calculate between similar terms $ $
$6 \color{#FF6800}{ - } \color{#FF6800}{ 7 } \color{#FF6800}{ i }$
