\frac{2\left(-2-x\right)}{-1-x}+\frac{2x}{x+1}
-1 olish uchun -2 va 1'ni qo'shing.
\frac{-2\left(-2-x\right)}{x+1}+\frac{2x}{x+1}
Ifodalarni qo‘shish yoki ayirish uchun ularni yoyib, maxrajlarini bir xil qiling. -1-x va x+1 ning eng kichik umumiy karralisi x+1. \frac{2\left(-2-x\right)}{-1-x} ni \frac{-1}{-1} marotabaga ko'paytirish.
\frac{-2\left(-2-x\right)+2x}{x+1}
\frac{-2\left(-2-x\right)}{x+1} va \frac{2x}{x+1} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.
\frac{4+2x+2x}{x+1}
-2\left(-2-x\right)+2x ichidagi ko‘paytirishlarni bajaring.
\frac{4+4x}{x+1}
4+2x+2x kabi iboralarga o‘xshab birlashtiring.
\frac{4\left(x+1\right)}{x+1}
\frac{4+4x}{x+1} ichida hali faktorlanmagan ifodalarni faktorlang.
