The given integral is:

\[
\int (3x^2 + 8x - 2) \, dx
\]

To solve this, we apply the power rule of integration, which states that:

\[
\int x^n \, dx = \frac{x^{n+1}}{n+1} + C
\]

Now, integrate each term separately:

1. \(\int 3x^2 \, dx = 3 \cdot \frac{x^3}{3} = x^3\)
2. \(\int 8x \, dx = 8 \cdot \frac{x^2}{2} = 4x^2\)
3. \(\int (-2) \, dx = -2x\)

Now, putting it all together:

\[
x^3 + 4x^2 - 2x + C
\]

where \(C\) is the constant of integration.

Thus, the solution is:

\[
x^3 + 4x^2 - 2x + C
\]
