\[\frac{a(x - a)}{x - 2} = 0,\ \ x \neq 2\]
\[a(x - a) = 0\]
\[a = 0,\ \ x - a = 0\]
\[\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x = a\]
\[Ответ:\ a = x = 2 \Longrightarrow нет\ \]
\[решения,\ \]
\[\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ a = 0 \Longrightarrow x - любое,\]
\(a \neq 2;a \neq 0 \Longrightarrow x = a.\)
