Kua tāruatia ki te papatopenga
3\left(a^{2}-16b^{2}\right)
Tauwehea te 3.
\left(a-4b\right)\left(a+4b\right)
Whakaarohia te a^{2}-16b^{2}. Tuhia anō te a^{2}-16b^{2} hei a^{2}-\left(4b\right)^{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-4b\right)\left(a+4b\right)
Me tuhi anō te kīanga whakatauwehe katoa.
