Kua tāruatia ki te papatopenga
-100+36x^{2}\leq 0
Me whakarea te koreōrite ki te -1 kia tōrunga ai te tau whakarea o te pū tino teitei i 100-36x^{2}. I te mea he tōraro a -1, ka huri te ahunga koreōrite.
x^{2}\leq \frac{25}{9}
Me tāpiri te \frac{25}{9} ki ngā taha e rua.
x^{2}\leq \left(\frac{5}{3}\right)^{2}
Tātaitia te pūtakerua o \frac{25}{9} kia tae ki \frac{5}{3}. Tuhia anō te \frac{25}{9} hei \left(\frac{5}{3}\right)^{2}.
|x|\leq \frac{5}{3}
E mau ana te koreōrite mō |x|\leq \frac{5}{3}.
x\in \begin{bmatrix}-\frac{5}{3},\frac{5}{3}\end{bmatrix}
Tuhia anō te |x|\leq \frac{5}{3} hei x\in \left[-\frac{5}{3},\frac{5}{3}\right].
