V^2=u^2r eching

$$V ^ { 2 } = u ^ { 2 } r$$

r uchun yechish

$$\left\{\begin{matrix}r=\left(\frac{V}{u}\right)^{2}\text{, }&u\neq 0\\r\in \mathrm{R}\text{, }&V=0\text{ and }u=0\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$u^{2}r=V^{2}$$

Ikki tarafini u^{2} ga bo‘ling.

$$\frac{u^{2}r}{u^{2}}=\frac{V^{2}}{u^{2}}$$

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

$$r=\frac{V^{2}}{u^{2}}$$

V uchun yechish

$$\left\{\begin{matrix}V=\sqrt{r}u\text{; }V=-\sqrt{r}u\text{, }&r\geq 0\\V=0\text{, }&u=0\end{matrix}\right,$$
