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.

$$-\left(b-3a^{2}\right)\left(9u^{4}+3bu^{2}+b^{2}\right)$$

Fairsingigh an slonn.

$$27a^{2}u^{4}-9bu^{4}+9ba^{2}u^{2}-3b^{2}u^{2}+3a^{2}b^{2}-b^{3}$$
