Whakaoti i te -x(x-2)(x-5)

$$- x ( x - 2 ) ( x - 5 )$$

Aromātai

$$-x\left(x-5\right)\left(x-2\right)$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te -x ki te x-2.

$$\left(\left(-x\right)x-2\left(-x\right)\right)\left(x-5\right)$$

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

$$\left(\left(-x\right)x+2x\right)\left(x-5\right)$$

Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o \left(-x\right)x+2x ki ia tau o x-5.

$$\left(-x\right)x^{2}-5\left(-x\right)x+2x^{2}-10x$$

Whakareatia te -5 ki te -1, ka 5.

$$\left(-x\right)x^{2}+5xx+2x^{2}-10x$$

Whakareatia te x ki te x, ka x^{2}.

$$\left(-x\right)x^{2}+5x^{2}+2x^{2}-10x$$

Pahekotia te 5x^{2} me 2x^{2}, ka 7x^{2}.

$$\left(-x\right)x^{2}+7x^{2}-10x$$

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.

$$-x^{3}+7x^{2}-10x$$

Whakaroha

$$-\left(x^{3}-7x^{2}+10x\right)$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te -x ki te x-2.

$$\left(\left(-x\right)x-2\left(-x\right)\right)\left(x-5\right)$$

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

$$\left(\left(-x\right)x+2x\right)\left(x-5\right)$$

Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o \left(-x\right)x+2x ki ia tau o x-5.

$$\left(-x\right)x^{2}-5\left(-x\right)x+2x^{2}-10x$$

Whakareatia te -5 ki te -1, ka 5.

$$\left(-x\right)x^{2}+5xx+2x^{2}-10x$$

Whakareatia te x ki te x, ka x^{2}.

$$\left(-x\right)x^{2}+5x^{2}+2x^{2}-10x$$

Pahekotia te 5x^{2} me 2x^{2}, ka 7x^{2}.

$$\left(-x\right)x^{2}+7x^{2}-10x$$

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.

$$-x^{3}+7x^{2}-10x$$
