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