$\frac{x - 1}{1 - x}$

Step 1

Factor $- 1$ out of $x$ .

$\frac{- 1 (- x) - 1}{1 - x}$

Step 2

Rewrite $- 1$ as $- 1 (1)$ .

$\frac{- 1 (- x) - 1 (1)}{1 - x}$

Step 3

Factor $- 1$ out of $- 1 (- x) - 1 (1)$ .

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

Step 4

Reorder terms.

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

Step 5

Cancel the common factor.

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

Step 6

Divide $- 1$ by $1$ .

$- 1$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
