Céimeanna Réitigh

Aithin na fachtóirí ar fad agus a gcumhacht is airde i ngach slonn. Iolraigh na cumhachtaí fachtóirí is airde chun an t-iolraí is lú coitianta a fháil.

$$-4\left(p-q\right)\left(p+q\right)b^{2}\left(a^{2}+c^{2}\right)$$

Fairsingigh an slonn.

$$-4a^{2}b^{2}p^{2}-4b^{2}c^{2}p^{2}+4a^{2}b^{2}q^{2}+4b^{2}c^{2}q^{2}$$

Luacháil
