Tauwehe
\frac{\left(a-4s\right)\left(4s+a\right)}{4}
Aromātai
\frac{a^{2}}{4}-4s^{2}

Kua tāruatia ki te papatopenga
\frac{a^{2}-16s^{2}}{4}
Tauwehea te \frac{1}{4}.
\left(a-4s\right)\left(a+4s\right)
Whakaarohia te a^{2}-16s^{2}. Tuhia anō te a^{2}-16s^{2} hei a^{2}-\left(4s\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(-4s+a\right)\left(4s+a\right)
Whakaraupapatia anō ngā kīanga tau.
\frac{\left(-4s+a\right)\left(4s+a\right)}{4}
Me tuhi anō te kīanga whakatauwehe katoa.
