化简 2/((x-1/x))-((1/x))/((1-1/x))

解答

化简

\frac{2}{( x - \frac{1}{x} )} - \frac{( \frac{1}{x} )}{( 1 - \frac{1}{x} )}

\frac{2 x}{x ^{2} - 1} - \frac{1}{x - 1}

求解步骤

\frac{2}{x - \frac{1}{x}} - \frac{\frac{1}{x}}{1 - \frac{1}{x}}

\frac{2}{x - \frac{1}{x}} = \frac{2 x}{x ^{2} - 1}

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

= \frac{2 x}{x ^{2} - 1} - \frac{1}{x - 1}
