5 raruraru e ōrite ana ki:
\frac { 6 x } { x ^ { 2 } - 9 } - \frac { 3 } { x + 3 } =
Tohaina
Kua tāruatia ki te papatopenga
\frac{6x}{\left(x-3\right)\left(x+3\right)}-\frac{3}{x+3}
Tauwehea te x^{2}-9.
\frac{6x}{\left(x-3\right)\left(x+3\right)}-\frac{3\left(x-3\right)}{\left(x-3\right)\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 \left(x-3\right)\left(x+3\right) me x+3 ko \left(x-3\right)\left(x+3\right). Whakareatia \frac{3}{x+3} ki te \frac{x-3}{x-3}.
\frac{6x-3\left(x-3\right)}{\left(x-3\right)\left(x+3\right)}
Tā te mea he rite te tauraro o \frac{6x}{\left(x-3\right)\left(x+3\right)} me \frac{3\left(x-3\right)}{\left(x-3\right)\left(x+3\right)}, me tango rāua mā te tango i ō raua taurunga.
\frac{6x-3x+9}{\left(x-3\right)\left(x+3\right)}
Mahia ngā whakarea i roto o 6x-3\left(x-3\right).
\frac{3x+9}{\left(x-3\right)\left(x+3\right)}
Whakakotahitia ngā kupu rite i 6x-3x+9.
\frac{3\left(x+3\right)}{\left(x-3\right)\left(x+3\right)}
Me whakatauwehe ngā kīanga kāore anō i whakatauwehea i roto o \frac{3x+9}{\left(x-3\right)\left(x+3\right)}.
\frac{3}{x-3}
Me whakakore tahi te x+3 i te taurunga me te tauraro.
