(2-x)^2=x^2 eching

$$( 2 - x ) ^ { 2 } = x ^ { 2 }$$

x uchun yechish

$$x=1$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\left(a-b\right)^{2}=a^{2}-2ab+b^{2} binom teoremasini \left(2-x\right)^{2} kengaytirilishi uchun ishlating.

$$4-4x+x^{2}=x^{2}$$

Ikkala tarafdan x^{2} ni ayirish.

$$4-4x+x^{2}-x^{2}=0$$

0 ni olish uchun x^{2} va -x^{2} ni birlashtirish.

$$4-4x=0$$

Ikkala tarafdan 4 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$-4x=-4$$

Ikki tarafini -4 ga bo‘ling.

$$x=\frac{-4}{-4}$$

1 ni olish uchun -4 ni -4 ga bo‘ling.

$$x=1$$
