x uchun yechish
\left\{\begin{matrix}x=-3\text{, }&f=0\\x=\frac{1}{f}\text{, }&f>0\text{ or }f<-\frac{1}{3}\\x=-\frac{1}{f}\text{, }&f>0\text{ and }f<\frac{1}{3}\end{matrix}\right,

xf=sign(x+3)
Tenglama standart shaklda.
\frac{xf}{x}=\frac{sign(x+3)}{x}
Ikki tarafini x ga bo‘ling.
f=\frac{sign(x+3)}{x}
x ga bo'lish x ga ko'paytirishni bekor qiladi.
