Kua tāruatia ki te papatopenga
\frac{25a^{2}-1}{25}
Tauwehea te \frac{1}{25}.
\left(5a-1\right)\left(5a+1\right)
Whakaarohia te 25a^{2}-1. Tuhia anō te 25a^{2}-1 hei \left(5a\right)^{2}-1^{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).
\frac{\left(5a-1\right)\left(5a+1\right)}{25}
Me tuhi anō te kīanga whakatauwehe katoa.
