9x^2+8y-1=0 eching

$$9 x ^ { 2 } + 8 y - 1 = 0$$

y uchun yechish

$$y=\frac{1-9x^{2}}{8}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan 9x^{2} ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$8y-1=-9x^{2}$$

1 ni ikki tarafga qo’shing.

$$8y=-9x^{2}+1$$

Tenglama standart shaklda.

$$8y=1-9x^{2}$$

Ikki tarafini 8 ga bo‘ling.

$$\frac{8y}{8}=\frac{1-9x^{2}}{8}$$

8 ga bo'lish 8 ga ko'paytirishni bekor qiladi.

$$y=\frac{1-9x^{2}}{8}$$

x uchun yechish (complex solution)

$$x=-\frac{\sqrt{1-8y}}{3}$$

$$x=\frac{\sqrt{1-8y}}{3}$$

x uchun yechish

$$x=\frac{\sqrt{1-8y}}{3}$$

$$x=-\frac{\sqrt{1-8y}}{3}\text{, }y\leq \frac{1}{8}$$
