5/(xy-y^2)=0

解答

\frac{5}{x y - y ^{2}} = 0

无解; x y - y^{2} \neq = 0

求解步骤

\frac{5}{x y - y ^{2}} = 0

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

5 = 0

两侧不相等

无解; x y - y^{2} \neq = 0

\frac{x}{3} - 2 = \frac{6}{x}

\frac{x + 4}{x + 3} = 4

so l v e f or t, q = \frac{k w}{ab c t}

\frac{x + 4}{x + 3} = 0

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