I uchun yechish
\left\{\begin{matrix}I=-\frac{5t-D-30}{5st^{2}}\text{, }&s\neq 0\text{ and }t\neq 0\\I\in \mathrm{R}\text{, }&\left(D=-30\text{ and }t=0\right)\text{ or }\left(D=5t-30\text{ and }s=0\right)\end{matrix}\right,
D uchun yechish
D=5\left(Ist^{2}+t-6\right)
Baham ko'rish
Klipbordga nusxa olish
-30+5t+5t^{2}sI=D
Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.
5t+5t^{2}sI=D+30
30 ni ikki tarafga qo’shing.
5t^{2}sI=D+30-5t
Ikkala tarafdan 5t ni ayirish.
5st^{2}I=30+D-5t
Tenglama standart shaklda.
\frac{5st^{2}I}{5st^{2}}=\frac{30+D-5t}{5st^{2}}
Ikki tarafini 5t^{2}s ga bo‘ling.
I=\frac{30+D-5t}{5st^{2}}
5t^{2}s ga bo'lish 5t^{2}s ga ko'paytirishni bekor qiladi.
