8\left(v^{4}-81\right)
8 omili.
\left(v^{2}-9\right)\left(v^{2}+9\right)
Hisoblang: v^{4}-81. v^{4}-81 ni \left(v^{2}\right)^{2}-9^{2} sifatida qaytadan yozish. Kvadratlarning farqini ushbu formula bilan hisoblash mumkin: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
\left(v-3\right)\left(v+3\right)
Hisoblang: v^{2}-9. v^{2}-9 ni v^{2}-3^{2} sifatida qaytadan yozish. Kvadratlarning farqini ushbu formula bilan hisoblash mumkin: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
8\left(v-3\right)\left(v+3\right)\left(v^{2}+9\right)
Toʻliq ajratilgan ifodani qaytadan yozing. Koʻphadli v^{2}+9 faktorlanmagan, chunki unda ratsional ildizlar topilmadi.
