Kua tāruatia ki te papatopenga
\frac{1}{x+3}-\frac{x^{2}-7}{2\left(x+3\right)}
Tauwehea te 2x+6.
\frac{2}{2\left(x+3\right)}-\frac{x^{2}-7}{2\left(x+3\right)}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o x+3 me 2\left(x+3\right) ko 2\left(x+3\right). Whakareatia \frac{1}{x+3} ki te \frac{2}{2}.
\frac{2-\left(x^{2}-7\right)}{2\left(x+3\right)}
Tā te mea he rite te tauraro o \frac{2}{2\left(x+3\right)} me \frac{x^{2}-7}{2\left(x+3\right)}, me tango rāua mā te tango i ō raua taurunga.
\frac{2-x^{2}+7}{2\left(x+3\right)}
Mahia ngā whakarea i roto o 2-\left(x^{2}-7\right).
\frac{9-x^{2}}{2\left(x+3\right)}
Whakakotahitia ngā kupu rite i 2-x^{2}+7.
\frac{\left(x-3\right)\left(-x-3\right)}{2\left(x+3\right)}
Me whakatauwehe ngā kīanga kāore anō i whakatauwehea i roto o \frac{9-x^{2}}{2\left(x+3\right)}.
\frac{-\left(x-3\right)\left(x+3\right)}{2\left(x+3\right)}
Unuhia te tohu tōraro i roto o -3-x.
\frac{-\left(x-3\right)}{2}
Me whakakore tahi te x+3 i te taurunga me te tauraro.
\frac{-x+3}{2}
Hei kimi i te tauaro o x-3, kimihia te tauaro o ia taurangi.
