Kua tāruatia ki te papatopenga
\left(x^{2}-3\right)\left(x^{2}+3\right)
Tuhia anō te x^{4}-9 hei \left(x^{2}\right)^{2}-3^{2}. Ka taea te rerekētanga o ngā pūrua te whakatauwehe mā te ture: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right). Kāore i tauwehea ēnei pūrau i te mea kāhore ō rātou pūtake whakahau: x^{2}-3,x^{2}+3.
