$$4 E X ^ { 2 } + ( y - 5 ) ^ { 2 } = 16$$

E uchun yechish (complex solution)

$$\left\{\begin{matrix}E=-\frac{\left(y-9\right)\left(y-1\right)}{4X^{2}}\text{, }&X\neq 0\\E\in \mathrm{C}\text{, }&\left(y=1\text{ or }y=9\right)\text{ and }X=0\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\left(a-b\right)^{2}=a^{2}-2ab+b^{2} binom teoremasini \left(y-5\right)^{2} kengaytirilishi uchun ishlating.

$$4EX^{2}+y^{2}-10y+25=16$$

Ikkala tarafdan y^{2} ni ayirish.

$$4EX^{2}-10y+25=16-y^{2}$$

10y ni ikki tarafga qo’shing.

$$4EX^{2}+25=16-y^{2}+10y$$

Ikkala tarafdan 25 ni ayirish.

$$4EX^{2}=16-y^{2}+10y-25$$

-9 olish uchun 16 dan 25 ni ayirish.

$$4EX^{2}=-9-y^{2}+10y$$

Tenglama standart shaklda.

$$4X^{2}E=-y^{2}+10y-9$$

Ikki tarafini 4X^{2} ga bo‘ling.

$$\frac{4X^{2}E}{4X^{2}}=\frac{\left(1-y\right)\left(y-9\right)}{4X^{2}}$$

4X^{2} ga bo'lish 4X^{2} ga ko'paytirishni bekor qiladi.

$$E=\frac{\left(1-y\right)\left(y-9\right)}{4X^{2}}$$
