Step 1.1

Factor $3 x$ out of $3 x^{2}$ .

$3 x (x) - 6 x = 0$

Step 1.2

Factor $3 x$ out of $- 6 x$ .

$3 x (x) + 3 x (- 2) = 0$

Step 1.3

Factor $3 x$ out of $3 x (x) + 3 x (- 2)$ .

$3 x (x - 2) = 0$

Step 2

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

$x = 0$

$x - 2 = 0$

Step 3

Set $x$ equal to $0$ .

$x = 0$

Step 4

Set $x - 2$ equal to $0$ and solve for $x$ .

Step 4.1

Set $x - 2$ equal to $0$ .

$x - 2 = 0$

Step 4.2

Add $2$ to both sides of the equation.

$x = 2$

Step 5

The final solution is all the values that make $3 x (x - 2) = 0$ true.

$x = 0, 2$
