\frac{\left(x^{2}-7\right)\left(x-\sqrt{7}\right)}{\left(x+\sqrt{7}\right)\left(x-\sqrt{7}\right)}
Whakangāwaritia te tauraro o \frac{x^{2}-7}{x+\sqrt{7}} mā te whakarea i te taurunga me te tauraro ki te x-\sqrt{7}.
\frac{\left(x^{2}-7\right)\left(x-\sqrt{7}\right)}{x^{2}-\left(\sqrt{7}\right)^{2}}
Whakaarohia te \left(x+\sqrt{7}\right)\left(x-\sqrt{7}\right). Ka taea te whakareanga te panoni ki te rerekētanga o ngā pūrua mā te ture: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
\frac{\left(x^{2}-7\right)\left(x-\sqrt{7}\right)}{x^{2}-7}
Ko te pūrua o \sqrt{7} ko 7.
x-\sqrt{7}
Me whakakore tahi te x^{2}-7 i te taurunga me te tauraro.
