1/2-y+1/y eching

$$\frac{ 1 }{ 2-y } + \frac{ 1 }{ y }$$

Baholash

$$\frac{2}{y\left(2-y\right)}$$

Qisqa yechim qadamlari

Ifodalarni qo‘shish yoki ayirish uchun ularni yoyib, maxrajlarini bir xil qiling. 2-y va y ning eng kichik umumiy karralisi y\left(-y+2\right). \frac{1}{2-y} ni \frac{y}{y} marotabaga ko'paytirish. \frac{1}{y} ni \frac{-y+2}{-y+2} marotabaga ko'paytirish.

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

\frac{y}{y\left(-y+2\right)} va \frac{-y+2}{y\left(-y+2\right)} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

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

y-y+2 kabi iboralarga o‘xshab birlashtiring.

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

y\left(-y+2\right) ni kengaytirish.

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

y ga nisbatan hosilani topish

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