\frac{49x^{2}-25}{49}
\frac{1}{49} omili.
\left(7x-5\right)\left(7x+5\right)
Hisoblang: 49x^{2}-25. 49x^{2}-25 ni \left(7x\right)^{2}-5^{2} sifatida qaytadan yozish. Kvadratlarning farqini ushbu formula bilan hisoblash mumkin: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
\frac{\left(7x-5\right)\left(7x+5\right)}{49}
Toʻliq ajratilgan ifodani qaytadan yozing.
