Kua tāruatia ki te papatopenga
x^{2}\leq 5\times 7
Me whakarea ngā taha e rua ki te 7. I te mea he tōrunga te 7, kāore e huri te ahunga koreōrite.
x^{2}\leq 35
Whakareatia te 5 ki te 7, ka 35.
x^{2}\leq \left(\sqrt{35}\right)^{2}
Tātaitia te pūtakerua o 35 kia tae ki \sqrt{35}. Tuhia anō te 35 hei \left(\sqrt{35}\right)^{2}.
|x|\leq \sqrt{35}
E mau ana te koreōrite mō |x|\leq \sqrt{35}.
x\in \begin{bmatrix}-\sqrt{35},\sqrt{35}\end{bmatrix}
Tuhia anō te |x|\leq \sqrt{35} hei x\in \left[-\sqrt{35},\sqrt{35}\right].
