Question
**Determine** \( \mathcal{L}^{-1} \{ F \} \).

\[
sF(s) - 5F(s) = \frac{4s + 3}{s^2 + 10s + 25}
\]

\[ \mathcal{L}^{-1} \{ F \} = \boxed{\phantom{\text{solution here}}} \]

**Explanation:**

The expression at the top is a Laplace transform equation, where \( F(s) \) is the Laplace transform of a function and \( s \) is the complex frequency variable. The task is to determine the inverse Laplace transform \( \mathcal{L}^{-1} \{ F \} \).

The right side of the equation shows a rational function, \( \frac{4s + 3}{s^2 + 10s + 25} \), which is typically decomposed to find the inverse transform using known Laplace transform pairs and properties. To fully solve this, one would typically perform partial fraction decomposition or identify a standard form from Laplace tables.
