Kua tāruatia ki te papatopenga
\frac{\left(x^{2}-3x-2\right)x}{x}+\frac{2}{x}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia x^{2}-3x-2 ki te \frac{x}{x}.
\frac{\left(x^{2}-3x-2\right)x+2}{x}
Tā te mea he rite te tauraro o \frac{\left(x^{2}-3x-2\right)x}{x} me \frac{2}{x}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{x^{3}-3x^{2}-2x+2}{x}
Mahia ngā whakarea i roto o \left(x^{2}-3x-2\right)x+2.
