-1+7x^{2}\leq 0
1-7x^{2} musbatida eng katta quvvatni koeffitsientini aniqlash uchun tengsizlikni -1 ga koʻpaytiring. -1 manfiy boʻlgani uchun tengsizlikning yo‘nalishi o‘zgaradi.
x^{2}\leq \frac{1}{7}
\frac{1}{7} ni ikki tarafga qo’shing.
x^{2}\leq \left(\frac{\sqrt{7}}{7}\right)^{2}
\frac{1}{7} ning kvadrat ildizini hisoblab, \frac{\sqrt{7}}{7} natijaga ega bo‘ling. \frac{1}{7} ni \left(\frac{\sqrt{7}}{7}\right)^{2} sifatida qaytadan yozish.
|x|\leq \frac{\sqrt{7}}{7}
Tengsizlikda |x|\leq \frac{\sqrt{7}}{7} bor.
x\in \begin{bmatrix}-\frac{\sqrt{7}}{7},\frac{\sqrt{7}}{7}\end{bmatrix}
|x|\leq \frac{\sqrt{7}}{7} ni x\in \left[-\frac{\sqrt{7}}{7},\frac{\sqrt{7}}{7}\right] sifatida qaytadan yozish.
