-\frac{1}{3} va \frac{3}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\frac{-1-3}{3}}{2\left(-\frac{1}{3}\right)^{2}-\left(-\frac{1}{3}\right)^{2}}$$

-4 olish uchun -1 dan 3 ni ayirish.

$$\frac{-\frac{4}{3}}{2\left(-\frac{1}{3}\right)^{2}-\left(-\frac{1}{3}\right)^{2}}$$

2 daraja ko‘rsatkichini -\frac{1}{3} ga hisoblang va \frac{1}{9} ni qiymatni oling.

$$\frac{-\frac{4}{3}}{2\times \frac{1}{9}-\left(-\frac{1}{3}\right)^{2}}$$

\frac{2}{9} hosil qilish uchun 2 va \frac{1}{9} ni ko'paytirish.

$$\frac{-\frac{4}{3}}{\frac{2}{9}-\left(-\frac{1}{3}\right)^{2}}$$

2 daraja ko‘rsatkichini -\frac{1}{3} ga hisoblang va \frac{1}{9} ni qiymatni oling.

$$\frac{-\frac{4}{3}}{\frac{2}{9}-\frac{1}{9}}$$

\frac{2}{9} va \frac{1}{9} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-\frac{4}{3}}{\frac{2-1}{9}}$$

1 olish uchun 2 dan 1 ni ayirish.

$$\frac{-\frac{4}{3}}{\frac{1}{9}}$$

-\frac{4}{3} ni \frac{1}{9} ga bo'lish -\frac{4}{3} ga k'paytirish \frac{1}{9} ga qaytarish.

$$-\frac{4}{3}\times 9$$

-\frac{4}{3}\times 9 ni yagona kasrga aylantiring.

$$\frac{-4\times 9}{3}$$

-36 hosil qilish uchun -4 va 9 ni ko'paytirish.

$$\frac{-36}{3}$$

-12 ni olish uchun -36 ni 3 ga bo‘ling.
