`int ((x^2-2x+3)/x^4)dx`

Explanation

To solve the integral \( \int \frac{x^2 - 2x + 3}{x^4} \, dx \), we can break it down step by step.

### Step 1: Rewrite the integrand
First, we can simplify the integrand by dividing each term in the numerator by \( x^4 \):
\[ \int \frac{x^2}{x^4} - \frac{2x}{x^4} + \frac{3}{x^4} \, dx = \int \left( x^{-2} - 2x^{-3} + 3x^{-4} \right) \, dx \]
