x^{2}=\left(\sqrt{x}\times \frac{x+x}{x}\right)^{2}
Tenglamaning ikkala taraf kvadratini chiqarish.
x^{2}=\left(\sqrt{x}\times \frac{2x}{x}\right)^{2}
2x ni olish uchun x va x ni birlashtirish.
x^{2}=\left(\sqrt{x}\times 2\right)^{2}
Surat va maxrajdagi ikkala x ni qisqartiring.
x^{2}=\left(\sqrt{x}\right)^{2}\times 2^{2}
\left(\sqrt{x}\times 2\right)^{2} ni kengaytirish.
x^{2}=x\times 2^{2}
2 daraja ko‘rsatkichini \sqrt{x} ga hisoblang va x ni qiymatni oling.
x^{2}=x\times 4
2 daraja ko‘rsatkichini 2 ga hisoblang va 4 ni qiymatni oling.
x^{2}-x\times 4=0
Ikkala tarafdan x\times 4 ni ayirish.
x^{2}-4x=0
-4 hosil qilish uchun -1 va 4 ni ko'paytirish.
x\left(x-4\right)=0
x omili.
x=0 x=4
Tenglamani yechish uchun x=0 va x-4=0 ni yeching.
0=\sqrt{0}\times \frac{0+0}{0}
x=\sqrt{x}\times \frac{x+x}{x} tenglamasida x uchun 0 ni almashtiring. Bu ifoda noaniq.
4=\sqrt{4}\times \frac{4+4}{4}
x=\sqrt{x}\times \frac{x+x}{x} tenglamasida x uchun 4 ni almashtiring.
4=4
Qisqartirish. x=4 tenglamani qoniqtiradi.
x=4
x=\frac{x+x}{x}\sqrt{x} tenglamasi noyob yechimga ega.
