Me whakatauwehe ngā kīanga kāore anō i whakatauwehea i roto o \frac{a^{2}-b^{2}}{a^{2}-2ab+b^{2}}.

$$\frac{\left(a+b\right)\left(a-b\right)}{\left(a-b\right)^{2}}\times \frac{b-a}{a}$$

Me whakakore tahi te a-b i te taurunga me te tauraro.

$$\frac{a+b}{a-b}\times \frac{b-a}{a}$$

Me whakarea te \frac{a+b}{a-b} ki te \frac{b-a}{a} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{\left(a+b\right)\left(b-a\right)}{\left(a-b\right)a}$$

Unuhia te tohu tōraro i roto o b-a.

$$\frac{-\left(a+b\right)\left(a-b\right)}{a\left(a-b\right)}$$

Me whakakore tahi te a-b i te taurunga me te tauraro.

$$\frac{-\left(a+b\right)}{a}$$

Hei kimi i te tauaro o a+b, kimihia te tauaro o ia taurangi.
