Kua tāruatia ki te papatopenga
u^{2}\left(x^{2}-9\right)
Tauwehea te u^{2}.
\left(x-3\right)\left(x+3\right)
Whakaarohia te x^{2}-9. Tuhia anō te x^{2}-9 hei x^{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).
u^{2}\left(x-3\right)\left(x+3\right)
Me tuhi anō te kīanga whakatauwehe katoa.
