Tohaina
Kua tāruatia ki te papatopenga
\left(a^{2}-3\right)\left(a^{2}+3\right)
Tuhia anō te a^{4}-9 hei \left(a^{2}\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). Kāore i tauwehea ēnei pūrau i te mea kāhore ō rātou pūtake whakahau: a^{2}-3,a^{2}+3.
