$-a \times -a$
$a ^ { 2 }$
Organize polynomials
$\color{#FF6800}{ - } \color{#FF6800}{ a } \color{#FF6800}{ \times } \left ( \color{#FF6800}{ - } \color{#FF6800}{ a } \right )$
$ $ Organize the mononomial expression $ $
$\color{#FF6800}{ a } ^ { \color{#FF6800}{ 2 } }$
$a ^ { 2 }$
Organize using the law of exponent
$\color{#FF6800}{ - } a \times \left ( \color{#FF6800}{ - } a \right )$
$ $ Since negative numbers are multiplied by an even number, remove the (-) sign $ $
$a a$
$\color{#FF6800}{ a } \color{#FF6800}{ a }$
$ $ Use the law of exponent $ $
$\color{#FF6800}{ a } ^ { \color{#FF6800}{ 2 } }$
