w\left(g^{3}+8\right)
Tauwehea te w.
\left(g+2\right)\left(g^{2}-2g+4\right)
Whakaarohia te g^{3}+8. Tuhia anō te g^{3}+8 hei g^{3}+2^{3}. Ka taea te tapeke pūtoru te whakatauwehe mā te whakamahi i te ture: a^{3}+b^{3}=\left(a+b\right)\left(a^{2}-ab+b^{2}\right).
w\left(g+2\right)\left(g^{2}-2g+4\right)
Me tuhi anō te kīanga whakatauwehe katoa. Kāore te pūrau g^{2}-2g+4 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
