Whakaoti i te x^2geq25x

$$x ^ { 2 } \geq 25 x$$

Whakaoti mō x

$$x\in (-\infty,0]\cup [25,\infty)$$

Ngā Upane Otinga

Tangohia te 25x mai i ngā taha e rua.

$$x^{2}-25x\geq 0$$

Tauwehea te x.

$$x\left(x-25\right)\geq 0$$

Kia ≥0 te otinga, me ≤0 tahi, me ≥0 tahi rānei te x me te x-25. Whakaarohia te tauira ina he ≤0 tahi te x me te x-25.

$$x\leq 0 x-25\leq 0$$

Te otinga e whakaea i ngā koreōrite e rua ko x\leq 0.

$$x\leq 0$$

Whakaarohia te tauira ina he ≥0 tahi te x me te x-25.

$$x-25\geq 0 x\geq 0$$

Te otinga e whakaea i ngā koreōrite e rua ko x\geq 25.

$$x\geq 25$$

Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.

$$x\leq 0\text{; }x\geq 25$$
