$\left( \dfrac{ 1 }{ 2 } a+ \dfrac{ 2 }{ 3 } b \right) \left( \dfrac{ 1 }{ 2 } a- \dfrac{ 2 }{ 3 } b \right)$
$\dfrac { 9 a ^ { 2 } - 16 b ^ { 2 } } { 36 }$
Arrange the rational expression
$\left ( \color{#FF6800}{ \dfrac { 1 } { 2 } } \color{#FF6800}{ a } \color{#FF6800}{ + } \color{#FF6800}{ \dfrac { 2 } { 3 } } \color{#FF6800}{ b } \right ) \left ( \color{#FF6800}{ \dfrac { 1 } { 2 } } \color{#FF6800}{ a } \color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 2 } { 3 } } \color{#FF6800}{ b } \right )$
$ $ Calculate the multiplication expression $ $
