Kua tāruatia ki te papatopenga
\frac{8a^{3}-27}{27}
Tauwehea te \frac{1}{27}.
\left(2a-3\right)\left(4a^{2}+6a+9\right)
Whakaarohia te 8a^{3}-27. Tuhia anō te 8a^{3}-27 hei \left(2a\right)^{3}-3^{3}. Ka taea te rerekētanga o ngā pūtoru te whakatauwehe mā te whakamahi i te ture: p^{3}-q^{3}=\left(p-q\right)\left(p^{2}+pq+q^{2}\right).
\frac{\left(2a-3\right)\left(4a^{2}+6a+9\right)}{27}
Me tuhi anō te kīanga whakatauwehe katoa. Kāore te pūrau 4a^{2}+6a+9 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
