Sederhanakanlah $a frac {1} {3}$ x ( $a frac {1} {3}$ + $a - frac {1} {3}$ ) ….

Penyelesaian :

$a frac {1} {3}$ x ( $a frac {1} {3}$ + $a - frac {1} {3}$ )

= $a frac {1} {3}$ x ( $2a frac {1} {3}$ – $frac {1} {3}$ )

= $frac {3a + 1} {3}$ x ( $frac {6a + 1} {3}$ – $frac {1} {3}$ )

= $frac {3a + 1} {3}$ x $frac {6a + 1 - 1} {3}$

= $frac {3a + 1} {3}$ x $frac {6a } {3}$

= $frac {3a + 1} {3}$ x 2a

= $frac {6a^{2} + 2a } {3}$

= $frac {2 ( 3a^{2} + a ) } {3}$

= $frac {2 } {3} ( 3a^{2} + a )$

Jadi, Sederhanakanlah $a frac {1} {3}$ x ( $a frac {1} {3}$ + $a - frac {1} {3}$ ) = $frac {2 } {3} ( 3a^{2} + a )$

Semoga membantu ya 🙂
