The given expression is:

\[
\lim_{x \to \infty} \sqrt{6x^2 - 2x + 1} - 4x + 2
\]

To solve this limit as \( x \to \infty \), we'll follow these steps:

### Step 1: Approximate the dominant term
When \( x \to \infty \), the term \( 6x^2 \) inside the square root dominates over \( -2x + 1 \). Thus, we approximate:

\[
\sqrt{6x^2 - 2x + 1} \approx \sqrt{6x^2} = \sqrt{6} \cdot x
\]

### Step 2: Simplify the expression
Using the approximation, the limit becomes:

\[
\lim_{x \to \infty} \left( \sqrt{6} \cdot x - 4x + 2 \right)
\]

### Step 3: Combine terms
Now, combine the \( x \)-terms:

\[
\lim_{x \to \infty} \left( (\sqrt{6} - 4) x + 2 \right)
\]

### Step 4: Evaluate the limit
As \( x \to \infty \), if \( \sqrt{6} - 4 \) is negative, the linear term will dominate and tend to negative infinity. Let's compute \( \sqrt{6} \):

\[
\sqrt{6} \approx 2.449
\]

Thus, \( \sqrt{6} - 4 \approx 2.449 - 4 = -1.551 \).

Therefore, the limit is:

\[
\lim_{x \to \infty} -1.551x + 2 = -\infty
\]

### Conclusion:
\[
\lim_{x \to \infty} \sqrt{6x^2 - 2x + 1} - 4x + 2 = -\infty
\]
