Solution

expand

\frac{9 ( x + 9 )}{x}

Solution

9 + \frac{81}{x}

Solution steps

\frac{9 ( x + 9 )}{x}

Expand

9 (x + 9) : 9 x + 81

= \frac{9 x + 81}{x}

Apply the fraction rule:

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

\frac{9 x + 81}{x} = \frac{9 x}{x} + \frac{81}{x}

= \frac{9 x}{x} + \frac{81}{x}

Cancel

\frac{9 x}{x} : 9

= 9 + \frac{81}{x}
