5 raruraru e ōrite ana ki:
\frac { 2 x } { x ^ { 2 } - 1 } + \frac { x } { x + 1 }
Tohaina
Kua tāruatia ki te papatopenga
\frac{2x}{\left(x-1\right)\left(x+1\right)}+\frac{x}{x+1}
Tauwehea te x^{2}-1.
\frac{2x}{\left(x-1\right)\left(x+1\right)}+\frac{x\left(x-1\right)}{\left(x-1\right)\left(x+1\right)}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o \left(x-1\right)\left(x+1\right) me x+1 ko \left(x-1\right)\left(x+1\right). Whakareatia \frac{x}{x+1} ki te \frac{x-1}{x-1}.
\frac{2x+x\left(x-1\right)}{\left(x-1\right)\left(x+1\right)}
Tā te mea he rite te tauraro o \frac{2x}{\left(x-1\right)\left(x+1\right)} me \frac{x\left(x-1\right)}{\left(x-1\right)\left(x+1\right)}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{2x+x^{2}-x}{\left(x-1\right)\left(x+1\right)}
Mahia ngā whakarea i roto o 2x+x\left(x-1\right).
\frac{x+x^{2}}{\left(x-1\right)\left(x+1\right)}
Whakakotahitia ngā kupu rite i 2x+x^{2}-x.
\frac{x\left(x+1\right)}{\left(x-1\right)\left(x+1\right)}
Me whakatauwehe ngā kīanga kāore anō i whakatauwehea i roto o \frac{x+x^{2}}{\left(x-1\right)\left(x+1\right)}.
\frac{x}{x-1}
Me whakakore tahi te x+1 i te taurunga me te tauraro.
