Whakarea ka paheko i ngā kīanga tau ōrite.
\left(x-2\right)\left(x^{2}+2x+4\right)
Tuhia anō te x^{3}-8 hei x^{3}-2^{3}. Ka taea te rerekētanga o ngā pūtoru te whakatauwehe mā te whakamahi i te ture: a^{3}-b^{3}=\left(a-b\right)\left(a^{2}+ab+b^{2}\right). Kāore te pūrau x^{2}+2x+4 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
x^{3}-8
Tātaihia te 2 mā te pū o 3, kia riro ko 8.
