$f (x) = - x (x - 1) {(x + 1)}^{2}$

Step 1

Set $- x (x - 1) {(x + 1)}^{2}$ equal to $0$ .

$- x (x - 1) {(x + 1)}^{2} = 0$

Step 2

Solve for $x$ .

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 $0$ .

$x = 0$

$x - 1 = 0$

${(x + 1)}^{2} = 0$

Step 2.2

Set $x$ equal to $0$ .

$x = 0$

Step 2.3

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

Step 2.3.1

Set $x - 1$ equal to $0$ .

$x - 1 = 0$

Step 2.3.2

Add $1$ to both sides of the equation.

$x = 1$

Step 2.4

Set ${(x + 1)}^{2}$ equal to $0$ and solve for $x$ .

Step 2.4.1

Set ${(x + 1)}^{2}$ equal to $0$ .

${(x + 1)}^{2} = 0$

Step 2.4.2

Solve ${(x + 1)}^{2} = 0$ for $x$ .

Step 2.4.2.1

Set the $x + 1$ equal to $0$ .

$x + 1 = 0$

Step 2.4.2.2

Subtract $1$ from both sides of the equation.

$x = - 1$

Step 2.5

The final solution is all the values that make $- x (x - 1) {(x + 1)}^{2} = 0$ true.

$x = 0, 1, - 1$
