$$36 y \div 12 + 18 \div ( - 27 y )$$

Baholash

$$3y-\frac{2}{3y}$$

Qisqa yechim qadamlari

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

$$3y+\frac{18}{-27y}$$

Ifodalarni qo‘shish yoki ayirish uchun ularni yoyib, maxrajlarini bir xil qiling. 3y ni \frac{-27y}{-27y} marotabaga ko'paytirish.

$$\frac{3y\left(-27\right)y}{-27y}+\frac{18}{-27y}$$

\frac{3y\left(-27\right)y}{-27y} va \frac{18}{-27y} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{3y\left(-27\right)y+18}{-27y}$$

3y\left(-27\right)y+18 ichidagi ko‘paytirishlarni bajaring.

$$\frac{-81y^{2}+18}{-27y}$$

\frac{-81y^{2}+18}{-27y} ichida hali faktorlanmagan ifodalarni faktorlang.

$$\frac{9\left(-9y^{2}+2\right)}{-27y}$$

Surat va maxrajdagi ikkala 9 ni qisqartiring.

$$\frac{-9y^{2}+2}{-3y}$$

Omil

$$\frac{9y^{2}-2}{3y}$$
