Tauwehea te 2.
\left(a-3\right)\left(a^{2}+3a+9\right)
Whakaarohia te a^{3}-27. Tuhia anō te a^{3}-27 hei a^{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).
2\left(a-3\right)\left(a^{2}+3a+9\right)
Me tuhi anō te kīanga whakatauwehe katoa. Kāore te pūrau a^{2}+3a+9 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
