Whakaoti i te f(x)=x^2-7x+10,quadv

$$f ( x ) = x ^ { 2 } - 7 x + 10 , \quad v$$

Whakaoti mō f

$$f=x-7+\frac{10}{x}$$

$$x\neq 0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

He hanga arowhānui tō te whārite.

$$xf=x^{2}-7x+10$$

Whakawehea ngā taha e rua ki te x.

$$\frac{xf}{x}=\frac{\left(x-5\right)\left(x-2\right)}{x}$$

Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.

$$f=\frac{\left(x-5\right)\left(x-2\right)}{x}$$

Whakawehe \left(-5+x\right)\left(-2+x\right) ki te x.

$$f=x-7+\frac{10}{x}$$

Whakaoti mō x (complex solution)

$$x=\frac{-\sqrt{f^{2}+14f+9}+f+7}{2}$$

$$x=\frac{\sqrt{f^{2}+14f+9}+f+7}{2}$$

Whakaoti mō x

$$x=\frac{-\sqrt{f^{2}+14f+9}+f+7}{2}$$

$$x=\frac{\sqrt{f^{2}+14f+9}+f+7}{2}\text{, }f\geq 2\sqrt{10}-7\text{ or }f\leq -2\sqrt{10}-7$$
