expand (x-2)/(2x)

Solution

expand

\frac{x - 2}{2 x}

Solution

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

Solution steps

\frac{x - 2}{2 x}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

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

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

Cancel

\frac{x}{2 x} : \frac{1}{2}

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

Divide the numbers:

\frac{2}{2} = 1

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