x=-9-\frac{\sqrt{81-4\times 1\left(-22\right)}}{2\times 1}
2 daraja ko‘rsatkichini 9 ga hisoblang va 81 ni qiymatni oling.
x=-9-\frac{\sqrt{81-4\left(-22\right)}}{2\times 1}
4 hosil qilish uchun 4 va 1 ni ko'paytirish.
x=-9-\frac{\sqrt{81-\left(-88\right)}}{2\times 1}
-88 hosil qilish uchun 4 va -22 ni ko'paytirish.
x=-9-\frac{\sqrt{81+88}}{2\times 1}
-88 ning teskarisi 88 ga teng.
x=-9-\frac{\sqrt{169}}{2\times 1}
169 olish uchun 81 va 88'ni qo'shing.
x=-9-\frac{13}{2\times 1}
169 ning kvadrat ildizini hisoblab, 13 natijaga ega bo‘ling.
x=-9-\frac{13}{2}
2 hosil qilish uchun 2 va 1 ni ko'paytirish.
x=-\frac{18}{2}-\frac{13}{2}
-9 ni -\frac{18}{2} kasrga o‘giring.
x=\frac{-18-13}{2}
-\frac{18}{2} va \frac{13}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.
x=-\frac{31}{2}
-31 olish uchun -18 dan 13 ni ayirish.
