Whakaoti i te x_1^2-2-(x-08)=-2(09+x)

$$x _ { 1 } ^ { 2 } - 2 - ( x - 08 ) = - 2 ( 09 + x )$$

Whakaoti mō x

$$x=2-x_{1}^{2}$$

Ngā Upane Otinga

Whakareatia te 0 ki te 8, ka 0.

$$x_{1}^{2}-2-\left(x-0\right)=-2\left(0\times 9+x\right)$$

Whakareatia te 0 ki te 9, ka 0.

$$x_{1}^{2}-2-\left(x-0\right)=-2x$$

Me tāpiri te 2x ki ngā taha e rua.

$$x_{1}^{2}-2-\left(x-0\right)+2x=0$$

Whakaraupapatia anō ngā kīanga tau.

$$x_{1}^{2}-2-x+2x=0$$

Pahekotia te -x me 2x, ka x.

$$x_{1}^{2}-2+x=0$$

Tangohia te x_{1}^{2} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$-2+x=-x_{1}^{2}$$

Me tāpiri te 2 ki ngā taha e rua.

$$x=-x_{1}^{2}+2$$

Whakaoti mō x_1 (complex solution)

$$x_{1}=-\sqrt{2-x}$$

$$x_{1}=\sqrt{2-x}$$

Whakaoti mō x_1

$$x_{1}=\sqrt{2-x}$$

$$x_{1}=-\sqrt{2-x}\text{, }x\leq 2$$
