\frac{\left(x+1\right)\left(x-1\right)}{x}
\frac{x+1}{x} ni \frac{1}{x-1} ga bo'lish \frac{x+1}{x} ga k'paytirish \frac{1}{x-1} ga qaytarish.
\frac{x^{2}-1^{2}}{x}
Hisoblang: \left(x+1\right)\left(x-1\right). Ko‘paytirish qoida yordamida turli kvadratlarga aylantirilishi mumkin: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
\frac{x^{2}-1}{x}
2 daraja ko‘rsatkichini 1 ga hisoblang va 1 ni qiymatni oling.
