Whakaoti i te (x-y+1)(x-y-1)

$$( x - y + 1 ) ( x - y - 1 )$$

Aromātai

$$\left(x-y\right)^{2}-1$$

Ngā Upane Otinga

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}, ina a=x-y me b=1.

$$\left(x-y\right)^{2}-1^{2}$$

Whakamahia te ture huarua \left(a-b\right)^{2}=a^{2}-2ab+b^{2} hei whakaroha \left(x-y\right)^{2}.

$$x^{2}-2xy+y^{2}-1^{2}$$

Tātaihia te 1 mā te pū o 2, kia riro ko 1.

$$x^{2}-2xy+y^{2}-1$$

Whakaroha

$$x^{2}-2xy+y^{2}-1$$
