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

$$( x + a - 1 ) ( x + a + 1 )$$

Aromātai

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

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+a me b=1.

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

Whakamahia te ture huarua \left(p+q\right)^{2}=p^{2}+2pq+q^{2} hei whakaroha \left(x+a\right)^{2}.

$$x^{2}+2xa+a^{2}-1^{2}$$

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

$$x^{2}+2xa+a^{2}-1$$

Whakaroha
