x^2+4x+4y=-8 eching

$$x ^ { 2 } + 4 x + 4 y = - 8$$

y uchun yechish

$$y=-\frac{x^{2}}{4}-x-2$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan x^{2} ni ayirish.

$$4x+4y=-8-x^{2}$$

Ikkala tarafdan 4x ni ayirish.

$$4y=-8-x^{2}-4x$$

Tenglama standart shaklda.

$$4y=-x^{2}-4x-8$$

Ikki tarafini 4 ga bo‘ling.

$$\frac{4y}{4}=\frac{-x^{2}-4x-8}{4}$$

4 ga bo'lish 4 ga ko'paytirishni bekor qiladi.

$$y=\frac{-x^{2}-4x-8}{4}$$

-8-x^{2}-4x ni 4 ga bo'lish.

$$y=-\frac{x^{2}}{4}-x-2$$

x uchun yechish (complex solution)

$$x=2\sqrt{-y-1}-2$$

$$x=-2\sqrt{-y-1}-2$$

x uchun yechish

$$x=2\sqrt{-y-1}-2$$

$$x=-2\sqrt{-y-1}-2\text{, }y\leq -1$$
