Kua tāruatia ki te papatopenga
\frac{1}{x}+\frac{\left(-2x-1\right)x}{x}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia -2x-1 ki te \frac{x}{x}.
\frac{1+\left(-2x-1\right)x}{x}
Tā te mea he rite te tauraro o \frac{1}{x} me \frac{\left(-2x-1\right)x}{x}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{1-2x^{2}-x}{x}
Mahia ngā whakarea i roto o 1+\left(-2x-1\right)x.
