The equation provided is:

\[
3 \cot^2(x) + 3 \cot(x) = 0
\]

To solve this equation, we can factor it.

### Step 1: Factor the equation
First, factor out the common factor, which is \( 3 \cot(x) \):

\[
3 \cot(x) [\cot(x) + 1] = 0
\]

Now, set each factor equal to zero:

1. \( 3 \cot(x) = 0 \)
2. \( \cot(x) + 1 = 0 \)

### Step 2: Solve each equation
1. \( 3 \cot(x) = 0 \)
   \[
   \cot(x) = 0
   \]
   The cotangent function is zero when \( x = \frac{\pi}{2} + n\pi \), where \( n \) is an integer.

2. \( \cot(x) + 1 = 0 \)
   \[
   \cot(x) = -1
   \]
   The cotangent function equals \(-1\) when \( x = \frac{3\pi}{4} + n\pi \), where \( n \) is an integer.

### Final Solution
The general solutions for \( x \) are:

- \( x = \frac{\pi}{2} + n\pi \) for the first equation.
- \( x = \frac{3\pi}{4} + n\pi \) for the second equation.

Thus, the solutions are:

\[
x = \frac{\pi}{2} + n\pi \quad \text{or} \quad x = \frac{3\pi}{4} + n\pi \quad \text{for integers} \, n.
\]
