Issolvi n(n+1)(n+2)

$$n ( n + 1 ) ( n + 2 )$$

Espandi

$$n^{3}+3n^{2}+2n$$

Passi tas-Soluzzjonijiet

Uża l-propjetà distributtiva biex timmultiplika n b'n+1.

$$\left(n^{2}+n\right)\left(n+2\right)$$

Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' n^{2}+n b'kull terminu ta' n+2.

$$n^{3}+2n^{2}+n^{2}+2n$$

Ikkombina 2n^{2} u n^{2} biex tikseb 3n^{2}.

$$n^{3}+3n^{2}+2n$$
