Step 2.1

If any individual factor on the left side of the equation is equal to $0$ , the entire expression will be equal to $0$ .

$x = 0$

$1 - x = 0$

Step 2.2

Set $x$ equal to $0$ .

$x = 0$

Step 2.3

Set $1 - x$ equal to $0$ and solve for $x$ .

Step 2.3.2.2.2.1

Dividing two negative values results in a positive value.

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

Step 2.3.2.2.2.2

Divide $x$ by $1$ .

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

Step 2.3.2.2.3

Simplify the right side.

Step 2.3.2.2.3.1

Divide $- 1$ by $- 1$ .

$x = 1$

Step 2.4

The final solution is all the values that make $x e (1 - x) = 0$ true.

$x = 0, 1$
