Kua tāruatia ki te papatopenga
\left(r-2\right)\left(r^{2}+2r+4\right)
Tuhia anō te r^{3}-8 hei r^{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 r^{2}+2r+4 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
