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