Evaluate: `int(x^3+5x^2+4x+1)/(x^2)\ dx`

Explanation

To evaluate the integral \(\int \frac{x^3 + 5x^2 + 4x + 1}{x^2} \, dx\), we can simplify the integrand by dividing each term in the numerator by \(x^2\).

### Step-by-step Solution:

1. **Simplify the integrand**:
\[ \frac{x^3 + 5x^2 + 4x + 1}{x^2} = \frac{x^3}{x^2} + \frac{5x^2}{x^2} + \frac{4x}{x^2} + \frac{1}{x^2} \]
