Passi tas-Soluzzjonijiet

Uża l-propjetà distributtiva biex timmultiplika m^{2}+m+1 b'm+1 u kkombina termini simili.

$$m^{3}+2m^{2}+2m+1+\left(m^{2}-m-1\right)\left(m-1\right)-2m\left(m^{2}+1\right)$$

Uża l-propjetà distributtiva biex timmultiplika m^{2}-m-1 b'm-1 u kkombina termini simili.

$$m^{3}+2m^{2}+2m+1+m^{3}-2m^{2}+1-2m\left(m^{2}+1\right)$$

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

$$2m^{3}+2m^{2}+2m+1-2m^{2}+1-2m\left(m^{2}+1\right)$$

Ikkombina 2m^{2} u -2m^{2} biex tikseb 0.

$$2m^{3}+2m+1+1-2m\left(m^{2}+1\right)$$

Żid 1 u 1 biex tikseb 2.

$$2m^{3}+2m+2-2m\left(m^{2}+1\right)$$

Uża l-propjetà distributtiva biex timmultiplika -2m b'm^{2}+1.

$$2m^{3}+2m+2-2m^{3}-2m$$

Ikkombina 2m^{3} u -2m^{3} biex tikseb 0.

$$2m+2-2m$$

Ikkombina 2m u -2m biex tikseb 0.
