Tohaina
Kua tāruatia ki te papatopenga
\frac{x+1}{x+7}-\frac{1}{x-2}
Me whakakore tahi te x i te taurunga me te tauraro.
\frac{\left(x+1\right)\left(x-2\right)}{\left(x-2\right)\left(x+7\right)}-\frac{x+7}{\left(x-2\right)\left(x+7\right)}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o x+7 me x-2 ko \left(x-2\right)\left(x+7\right). Whakareatia \frac{x+1}{x+7} ki te \frac{x-2}{x-2}. Whakareatia \frac{1}{x-2} ki te \frac{x+7}{x+7}.
\frac{\left(x+1\right)\left(x-2\right)-\left(x+7\right)}{\left(x-2\right)\left(x+7\right)}
Tā te mea he rite te tauraro o \frac{\left(x+1\right)\left(x-2\right)}{\left(x-2\right)\left(x+7\right)} me \frac{x+7}{\left(x-2\right)\left(x+7\right)}, me tango rāua mā te tango i ō raua taurunga.
\frac{x^{2}-2x+x-2-x-7}{\left(x-2\right)\left(x+7\right)}
Mahia ngā whakarea i roto o \left(x+1\right)\left(x-2\right)-\left(x+7\right).
\frac{x^{2}-2x-9}{\left(x-2\right)\left(x+7\right)}
Whakakotahitia ngā kupu rite i x^{2}-2x+x-2-x-7.
\frac{x^{2}-2x-9}{x^{2}+5x-14}
Whakarohaina te \left(x-2\right)\left(x+7\right).
\frac{x+1}{x+7}-\frac{1}{x-2}
Me whakakore tahi te x i te taurunga me te tauraro.
\frac{\left(x+1\right)\left(x-2\right)}{\left(x-2\right)\left(x+7\right)}-\frac{x+7}{\left(x-2\right)\left(x+7\right)}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o x+7 me x-2 ko \left(x-2\right)\left(x+7\right). Whakareatia \frac{x+1}{x+7} ki te \frac{x-2}{x-2}. Whakareatia \frac{1}{x-2} ki te \frac{x+7}{x+7}.
\frac{\left(x+1\right)\left(x-2\right)-\left(x+7\right)}{\left(x-2\right)\left(x+7\right)}
Tā te mea he rite te tauraro o \frac{\left(x+1\right)\left(x-2\right)}{\left(x-2\right)\left(x+7\right)} me \frac{x+7}{\left(x-2\right)\left(x+7\right)}, me tango rāua mā te tango i ō raua taurunga.
\frac{x^{2}-2x+x-2-x-7}{\left(x-2\right)\left(x+7\right)}
Mahia ngā whakarea i roto o \left(x+1\right)\left(x-2\right)-\left(x+7\right).
\frac{x^{2}-2x-9}{\left(x-2\right)\left(x+7\right)}
Whakakotahitia ngā kupu rite i x^{2}-2x+x-2-x-7.
\frac{x^{2}-2x-9}{x^{2}+5x-14}
Whakarohaina te \left(x-2\right)\left(x+7\right).
