a^{4}-a^{2}-2a+1-\frac{1}{a}
Tauwehe
\frac{a^{5}-a^{3}-2a^{2}+a-1}{a}
Tohaina
Kua tāruatia ki te papatopenga
\frac{\left(a^{4}-a^{2}-2a+1\right)a}{a}-\frac{1}{a}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia a^{4}-a^{2}-2a+1 ki te \frac{a}{a}.
\frac{\left(a^{4}-a^{2}-2a+1\right)a-1}{a}
Tā te mea he rite te tauraro o \frac{\left(a^{4}-a^{2}-2a+1\right)a}{a} me \frac{1}{a}, me tango rāua mā te tango i ō raua taurunga.
\frac{a^{5}-a^{3}-2a^{2}+a-1}{a}
Mahia ngā whakarea i roto o \left(a^{4}-a^{2}-2a+1\right)a-1.
