Tauwehe
\left(2ab-7n^{3}\right)\left(7n^{3}+2ab\right)
Aromātai
4\left(ab\right)^{2}-49n^{6}
Tohaina
Kua tāruatia ki te papatopenga
\left(2ab-7n^{3}\right)\left(2ab+7n^{3}\right)
Tuhia anō te 4a^{2}b^{2}-49n^{6} hei \left(2ab\right)^{2}-\left(7n^{3}\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).
\left(-7n^{3}+2ab\right)\left(7n^{3}+2ab\right)
Whakaraupapatia anō ngā kīanga tau.
