-a=sqrt{2a^2+3ab-10} eching

$$-a = \sqrt{ 2 { a }^{ 2 } +3ab-10 }$$

b uchun yechish

$$b=-\frac{a}{3}+\frac{10}{3a}$$

$$a<0$$

Ildizli tenglamalarni yechish qadamlari

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$\sqrt{2a^{2}+3ab-10}=-a$$

Tenglamaning ikkala taraf kvadratini chiqarish.

$$3ab+2a^{2}-10=a^{2}$$

Tenglamaning ikkala tarafidan 2a^{2}-10 ni ayirish.

$$3ab+2a^{2}-10-\left(2a^{2}-10\right)=a^{2}-\left(2a^{2}-10\right)$$

O‘zidan 2a^{2}-10 ayirilsa 0 qoladi.

$$3ab=a^{2}-\left(2a^{2}-10\right)$$

a^{2} dan 2a^{2}-10 ni ayirish.

$$3ab=10-a^{2}$$

Ikki tarafini 3a ga bo‘ling.

$$\frac{3ab}{3a}=\frac{10-a^{2}}{3a}$$

3a ga bo'lish 3a ga ko'paytirishni bekor qiladi.

$$b=\frac{10-a^{2}}{3a}$$

-a^{2}+10 ni 3a ga bo'lish.

$$b=-\frac{a}{3}+\frac{10}{3a}$$

a uchun yechish (complex solution)

$$\left\{\begin{matrix}a=\frac{-\sqrt{9b^{2}+40}-3b}{2}\text{, }&arg(\frac{-\sqrt{9b^{2}+40}-3b}{2})\geq \pi \\a=\frac{\sqrt{9b^{2}+40}-3b}{2}\text{, }&arg(\frac{\sqrt{9b^{2}+40}-3b}{2})\geq \pi \end{matrix}\right,$$

b uchun yechish (complex solution)

$$b=-\frac{a}{3}+\frac{10}{3a}$$

$$arg(a)\geq \pi \text{ and }a\neq 0$$

a uchun yechish

$$a=\frac{-\sqrt{9b^{2}+40}-3b}{2}$$

$$\left(\frac{\sqrt{9b^{2}+80}}{4}-\frac{\sqrt{9b^{2}+40}}{2}-\frac{3b}{4}\leq 0\text{ or }-\frac{\sqrt{9b^{2}+40}}{2}-\frac{\sqrt{9b^{2}+80}}{4}-\frac{3b}{4}\geq 0\right)\text{ and }b\leq \frac{\sqrt{9b^{2}+40}}{6}+\frac{3b}{2}$$
