Whakaoti i te a-a^2*a^3

$$a - a ^ { 2 } \times a ^ { 3 }$$

Tauwehe

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

Ngā Upane Otinga

Tauwehea te a.

$$a\left(1-aa^{3}\right)$$

Whakaarohia te 1-a^{4}. Tuhia anō te 1-a^{4} hei 1^{2}-\left(-a^{2}\right)^{2}. Ka taea te rerekētanga o ngā pūrua te whakatauwehe mā te ture: p^{2}-q^{2}=\left(p-q\right)\left(p+q\right).

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

Whakaraupapatia anō ngā kīanga tau.

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

Whakaarohia te -a^{2}+1. Tuhia anō te -a^{2}+1 hei 1^{2}-a^{2}. Ka taea te rerekētanga o ngā pūrua te whakatauwehe mā te ture: p^{2}-q^{2}=\left(p-q\right)\left(p+q\right).

$$\left(1-a\right)\left(1+a\right)$$

Whakaraupapatia anō ngā kīanga tau.

$$\left(-a+1\right)\left(a+1\right)$$

Me tuhi anō te kīanga whakatauwehe katoa. Kāore te pūrau a^{2}+1 i whakatauwehea i te mea kāhore ōna pūtake whakahau.

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

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 2 me te 3 kia riro ai te 5.
