Whakaoti i te (b^2+1)(-b)+(-b+1)(1-b^2)

$$( b ^ { 2 } + 1 ) ( - b ) + ( - b + 1 ) ( 1 - b ^ { 2 } )$$

Aromātai

$$1-2b-b^{2}$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te b^{2}+1 ki te -b.

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

Whakamahia te āhuatanga tohatoha hei whakarea te -b+1 ki te 1-b^{2}.

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

Whakareatia te -1 ki te -1, ka 1.

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

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 1 me te 2 kia riro ai te 3.

$$b^{2}\left(-b\right)-b-b+b^{3}+1-b^{2}$$

Pahekotia te -b me -b, ka 2\left(-b\right).

$$b^{2}\left(-b\right)+2\left(-b\right)+b^{3}+1-b^{2}$$

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 2 me te 1 kia riro ai te 3.

$$b^{3}\left(-1\right)+2\left(-1\right)b+b^{3}+1-b^{2}$$

Whakareatia te 2 ki te -1, ka -2.

$$b^{3}\left(-1\right)-2b+b^{3}+1-b^{2}$$

Pahekotia te b^{3}\left(-1\right) me b^{3}, ka 0.
