$2 a + b \color{#FF6800}{ - } \left ( \color{#FF6800}{ a } \color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ b } \right )$
 Change the symbol of each term in parentheses when there is a (-) symbol in front of parentheses 
$2 a + b \color{#FF6800}{ - } \color{#FF6800}{ a } + \color{#FF6800}{ 2 } \color{#FF6800}{ b }$
