2x^3+2x^2-5x+1=2x^3+2x^2-4x eching

$$2 x ^ { 3 } + 2 x ^ { 2 } - 5 x + 1 = 2 x ^ { 3 } + 2 x ^ { 2 } - 4 x$$

x uchun yechish

$$x=1$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan 2x^{3} ni ayirish.

$$2x^{3}+2x^{2}-5x+1-2x^{3}=2x^{2}-4x$$

0 ni olish uchun 2x^{3} va -2x^{3} ni birlashtirish.

$$2x^{2}-5x+1=2x^{2}-4x$$

Ikkala tarafdan 2x^{2} ni ayirish.

$$2x^{2}-5x+1-2x^{2}=-4x$$

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

$$-5x+1=-4x$$

4x ni ikki tarafga qo’shing.

$$-5x+1+4x=0$$

-x ni olish uchun -5x va 4x ni birlashtirish.

$$-x+1=0$$

Ikkala tarafdan 1 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$-x=-1$$

Ikkala tarafini -1 ga ko‘paytiring.

$$x=1$$
