x4+2x2+1=0 eching

$$x4+2x2+1=0$$

x_2 uchun yechish

$$x_{2}=\frac{-x_{4}-1}{2}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$2x_{2}+1=-x_{4}$$

Ikkala tarafdan 1 ni ayirish.

$$2x_{2}=-x_{4}-1$$

Ikki tarafini 2 ga bo‘ling.

$$\frac{2x_{2}}{2}=\frac{-x_{4}-1}{2}$$

2 ga bo'lish 2 ga ko'paytirishni bekor qiladi.

$$x_{2}=\frac{-x_{4}-1}{2}$$

x_4 uchun yechish

$$x_{4}=-2x_{2}-1$$

Yechim qadamlari

Ikkala tarafdan 2x_{2} ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$x_{4}+1=-2x_{2}$$

Ikkala tarafdan 1 ni ayirish.

$$x_{4}=-2x_{2}-1$$
