Whakaoti i te (1-lambda)(1-lambda)(2-lambda)+2-lambda

$$( 1 - \lambda ) ( 1 - \lambda ) ( 2 - \lambda ) + 2 - \lambda$$

Aromātai

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

Ngā Upane Otinga

Whakareatia te 1-\lambda ki te 1-\lambda , ka \left(1-\lambda \right)^{2}.

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

Whakamahia te ture huarua \left(a-b\right)^{2}=a^{2}-2ab+b^{2} hei whakaroha \left(1-\lambda \right)^{2}.

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

Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o 1-2\lambda +\lambda ^{2} ki ia tau o 2-\lambda .

$$2-\lambda -4\lambda +2\lambda ^{2}+2\lambda ^{2}-\lambda ^{3}+2-\lambda$$

Pahekotia te -\lambda me -4\lambda , ka -5\lambda .

$$2-5\lambda +2\lambda ^{2}+2\lambda ^{2}-\lambda ^{3}+2-\lambda$$

Pahekotia te 2\lambda ^{2} me 2\lambda ^{2}, ka 4\lambda ^{2}.

$$2-5\lambda +4\lambda ^{2}-\lambda ^{3}+2-\lambda$$

Tāpirihia te 2 ki te 2, ka 4.

$$4-5\lambda +4\lambda ^{2}-\lambda ^{3}-\lambda$$

Pahekotia te -5\lambda me -\lambda , ka -6\lambda .

$$4-6\lambda +4\lambda ^{2}-\lambda ^{3}$$

Whakaroha

$$4-6\lambda +4\lambda ^{2}-\lambda ^{3}$$
