Tauwehea te 9.
\left(a^{4}-3\right)\left(a^{4}+3\right)
Whakaarohia te a^{8}-9. Tuhia anō te a^{8}-9 hei \left(a^{4}\right)^{2}-3^{2}. Ka taea te rerekētanga o ngā pūrua te whakatauwehe mā te ture: p^{2}-q^{2}=\left(p-q\right)\left(p+q\right).
9\left(a^{4}-3\right)\left(a^{4}+3\right)
Me tuhi anō te kīanga whakatauwehe katoa. Kāore i tauwehea ēnei pūrau i te mea kāhore ō rātou pūtake whakahau: a^{4}-3,a^{4}+3.
