(x2)(x+2)=126 eching

$$(x2)(x+2)=126$$

x uchun yechish

$$x=-2+\frac{126}{x_{2}}$$

$$x_{2}\neq 0$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

x_{2} ga x+2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$x_{2}x+2x_{2}=126$$

Ikkala tarafdan 2x_{2} ni ayirish.

$$x_{2}x=126-2x_{2}$$

Ikki tarafini x_{2} ga bo‘ling.

$$\frac{x_{2}x}{x_{2}}=\frac{126-2x_{2}}{x_{2}}$$

x_{2} ga bo'lish x_{2} ga ko'paytirishni bekor qiladi.

$$x=\frac{126-2x_{2}}{x_{2}}$$

126-2x_{2} ni x_{2} ga bo'lish.

$$x=-2+\frac{126}{x_{2}}$$

x_2 uchun yechish

$$x_{2}=\frac{126}{x+2}$$

$$x\neq -2$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

x_{2} ga x+2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$x_{2}x+2x_{2}=126$$

x_{2}'ga ega bo'lgan barcha shartlarni birlashtirish.

$$\left(x+2\right)x_{2}=126$$

Ikki tarafini x+2 ga bo‘ling.

$$\frac{\left(x+2\right)x_{2}}{x+2}=\frac{126}{x+2}$$

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

$$x_{2}=\frac{126}{x+2}$$
