expand (3(x-4))/x

Solution

expand

\frac{3 ( x - 4 )}{x}

Solution

3 - \frac{12}{x}

Solution steps

\frac{3 ( x - 4 )}{x}

Expand

3 (x - 4) : 3 x - 12

= \frac{3 x - 12}{x}

Apply the fraction rule:

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

\frac{3 x - 12}{x} = \frac{3 x}{x} - \frac{12}{x}

= \frac{3 x}{x} - \frac{12}{x}

Cancel

\frac{3 x}{x} : 3

= 3 - \frac{12}{x}
