To differentiate the function \( f(x) = \ln^2(x) - 4\ln(x) + 3 \), we will use the chain rule and basic derivative rules.

### Step-by-step differentiation:

1. **Differentiate \( \ln^2(x) \)**:
   \[
   \frac{d}{dx} \ln^2(x) = 2\ln(x) \cdot \frac{d}{dx}[\ln(x)] = 2\ln(x) \cdot \frac{1}{x} = \frac{2\ln(x)}{x}
   \]

2. **Differentiate \( -4\ln(x) \)**:
   \[
   \frac{d}{dx}[-4\ln(x)] = -4 \cdot \frac{d}{dx}[\ln(x)] = -4 \cdot \frac{1}{x} = -\frac{4}{x}
   \]

3. **Differentiate the constant \( 3 \)**:
   \[
   \frac{d}{dx}[3] = 0
   \]

### Putting it all together:
\[
f'(x) = \frac{2\ln(x)}{x} - \frac{4}{x}
\]

Thus, the derivative of the function is:
\[
f'(x) = \frac{2\ln(x) - 4}{x}
\]
