(12)/(x^3)=0

解答

\frac{12}{x ^{3}} = 0

无解

求解步骤

\frac{12}{x ^{3}} = 0

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

12 = 0

两侧不相等

无解

x + \frac{3 x}{x - 1} = \frac{3}{x - 1}

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

\frac{1}{x + 6} + \frac{12}{x ^{2} - 36} = 1

\frac{y}{4} = \frac{9}{y}

6 (1 - x^{2})^{- 1} + 3 (1 - x)^{- 1} = 5 (x + 1)^{- 1}
