\frac{10\left(b+8\right)}{\left(b-1\right)\left(b+8\right)}-\frac{4\left(b-1\right)}{\left(b-1\right)\left(b+8\right)}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o b-1 me b+8 ko \left(b-1\right)\left(b+8\right). Whakareatia \frac{10}{b-1} ki te \frac{b+8}{b+8}. Whakareatia \frac{4}{b+8} ki te \frac{b-1}{b-1}.
\frac{10\left(b+8\right)-4\left(b-1\right)}{\left(b-1\right)\left(b+8\right)}
Tā te mea he rite te tauraro o \frac{10\left(b+8\right)}{\left(b-1\right)\left(b+8\right)} me \frac{4\left(b-1\right)}{\left(b-1\right)\left(b+8\right)}, me tango rāua mā te tango i ō raua taurunga.
\frac{10b+80-4b+4}{\left(b-1\right)\left(b+8\right)}
Mahia ngā whakarea i roto o 10\left(b+8\right)-4\left(b-1\right).
\frac{6b+84}{\left(b-1\right)\left(b+8\right)}
Whakakotahitia ngā kupu rite i 10b+80-4b+4.
\frac{6b+84}{b^{2}+7b-8}
Whakarohaina te \left(b-1\right)\left(b+8\right).
