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

Solution

simplify

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

Solution

\frac{3}{x - 1}

Solution steps

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

Apply the fraction rule:

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

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

Apply rule:

1 \cdot a = a

- 1 \cdot (x - 1) = - (x - 1)

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

Simplify

- (x - 1) + x + 2 : 3

= \frac{3}{x - 1}
