Tauwehea te 3.
\left(a^{2}-4\right)\left(a^{2}+4\right)
Whakaarohia te a^{4}-16. Tuhia anō te a^{4}-16 hei \left(a^{2}\right)^{2}-4^{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(a-2\right)\left(a+2\right)
Whakaarohia te a^{2}-4. Tuhia anō te a^{2}-4 hei a^{2}-2^{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).
3\left(a-2\right)\left(a+2\right)\left(a^{2}+4\right)
Me tuhi anō te kīanga whakatauwehe katoa. Kāore te pūrau a^{2}+4 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
