Tohaina
Kua tāruatia ki te papatopenga
x^{2}\leq \frac{9}{25}
Me tāpiri te \frac{9}{25} ki ngā taha e rua.
x^{2}\leq \left(\frac{3}{5}\right)^{2}
Tātaitia te pūtakerua o \frac{9}{25} kia tae ki \frac{3}{5}. Tuhia anō te \frac{9}{25} hei \left(\frac{3}{5}\right)^{2}.
|x|\leq \frac{3}{5}
E mau ana te koreōrite mō |x|\leq \frac{3}{5}.
x\in \begin{bmatrix}-\frac{3}{5},\frac{3}{5}\end{bmatrix}
Tuhia anō te |x|\leq \frac{3}{5} hei x\in \left[-\frac{3}{5},\frac{3}{5}\right].
