simplify (x+1-9/(x-1))*2

simplify

(x + 1 - \frac{9}{x - 1}) \cdot 2

\frac{2 ( x ^{2} - 10 )}{x - 1}

Solution steps

(x + 1 - \frac{9}{x - 1}) \cdot 2

Join

x + 1 - \frac{9}{x - 1} : \frac{x ^{2} - 10}{x - 1}

= \frac{x ^{2} - 10}{x - 1} \cdot 2

Apply the fraction rule:

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

= \frac{( x ^{2} - 10 ) \cdot 2}{x - 1}

= \frac{2 ( x ^{2} - 10 )}{x - 1}

(x + 1) (x - \frac{1}{3})
