Whakaoti i te 2x^2geq50

$$2x^2 \geq 50$$

Whakaoti mō x

$$x\in (-\infty,-5]\cup [5,\infty)$$

Ngā Upane Otinga

Whakawehea ngā taha e rua ki te 2. I te mea he tōrunga te 2, kāore e huri te ahunga koreōrite.

$$x^{2}\geq \frac{50}{2}$$

Whakawehea te 50 ki te 2, kia riro ko 25.

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

Tātaitia te pūtakerua o 25 kia tae ki 5. Tuhia anō te 25 hei 5^{2}.

$$x^{2}\geq 5^{2}$$

E mau ana te koreōrite mō |x|\geq 5.

$$|x|\geq 5$$

Tuhia anō te |x|\geq 5 hei x\leq -5\text{; }x\geq 5.

$$x\leq -5\text{; }x\geq 5$$
