7\left(ab^{2}-4a^{3}\right)
7 omili.
a\left(b^{2}-4a^{2}\right)
Hisoblang: ab^{2}-4a^{3}. a omili.
\left(b-2a\right)\left(b+2a\right)
Hisoblang: b^{2}-4a^{2}. b^{2}-4a^{2} ni b^{2}-\left(2a\right)^{2} sifatida qaytadan yozish. Kvadratlarning farqini ushbu formula bilan hisoblash mumkin: p^{2}-q^{2}=\left(p-q\right)\left(p+q\right).
