(3x)/(x-2)=0

解答

\frac{3 x}{x - 2} = 0

x = 0

求解步骤

\frac{3 x}{x - 2} = 0

\frac{f ( x )}{g ( x )} = 0 \Rightarrow f (x) = 0

3 x = 0

两边除以

3

x = 0

验证解

找到无定义的点（奇点）:

x = 2

将不在定义域的点与解相综合:

x = 0

\frac{- 11}{x} = \frac{- 22}{x + 4}

\frac{7}{x + 1} - \frac{4}{3 x - 2} = 1

so l v e f or y, x = \frac{4}{y}

so l v e f or x, g = \frac{( x - c )}{x}

\frac{m}{n} = \frac{8 m}{x n}
