49-k^{6} ni 7^{2}-\left(-k^{3}\right)^{2} sifatida qaytadan yozish. Kvadratlarning farqini ushbu formula bilan hisoblash mumkin: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
\left(k^{3}+7\right)\left(-k^{3}+7\right)
Shartlarni qayta saralash. Quyidagi koʻphadlar faktorlanmagan, ularda hech qanday ratsional ildizlar topilmadi: -k^{3}+7,k^{3}+7.
