\frac{\left(x^{2}-7\right)\left(x-\sqrt{7}\right)}{\left(x+\sqrt{7}\right)\left(x-\sqrt{7}\right)}
\frac{x^{2}-7}{x+\sqrt{7}} maxrajini x-\sqrt{7} orqali surat va maxrajini koʻpaytirish orqali ratsionallashtiring.
\frac{\left(x^{2}-7\right)\left(x-\sqrt{7}\right)}{x^{2}-\left(\sqrt{7}\right)^{2}}
Hisoblang: \left(x+\sqrt{7}\right)\left(x-\sqrt{7}\right). Ko‘paytirish qoida yordamida turli kvadratlarga aylantirilishi mumkin: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
\frac{\left(x^{2}-7\right)\left(x-\sqrt{7}\right)}{x^{2}-7}
\sqrt{7} kvadrati – 7.
x-\sqrt{7}
Surat va maxrajdagi ikkala x^{2}-7 ni qisqartiring.
