\frac{25a^{2}-1}{25}
\frac{1}{25} omili.
\left(5a-1\right)\left(5a+1\right)
Hisoblang: 25a^{2}-1. 25a^{2}-1 ni \left(5a\right)^{2}-1^{2} sifatida qaytadan yozish. Kvadratlarning farqini ushbu formula bilan hisoblash mumkin: p^{2}-q^{2}=\left(p-q\right)\left(p+q\right).
\frac{\left(5a-1\right)\left(5a+1\right)}{25}
Toʻliq ajratilgan ifodani qaytadan yozing.
