\left(b^{2}-49\right)\left(b^{2}+49\right)
Tuhia anō te b^{4}-2401 hei \left(b^{2}\right)^{2}-49^{2}. Ka taea te rerekētanga o ngā pūrua te whakatauwehe mā te ture: p^{2}-q^{2}=\left(p-q\right)\left(p+q\right).
\left(b-7\right)\left(b+7\right)
Whakaarohia te b^{2}-49. Tuhia anō te b^{2}-49 hei b^{2}-7^{2}. Ka taea te rerekētanga o ngā pūrua te whakatauwehe mā te ture: p^{2}-q^{2}=\left(p-q\right)\left(p+q\right).
\left(b-7\right)\left(b+7\right)\left(b^{2}+49\right)
Me tuhi anō te kīanga whakatauwehe katoa. Kāore te pūrau b^{2}+49 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
