Question
If \( f(x) = \left( x^2 + 4x + 5 \right)^2 \), then

\[ f'(x) = 4x^3 + 24x^2 + 52x + 40 \]

\( f'(2) = \) 

Explanation:
- The function \( f(x) \) is given as the square of the quadratic expression \( x^2 + 4x + 5 \).
- The derivative \( f'(x) \) is a cubic polynomial \( 4x^3 + 24x^2 + 52x + 40 \).
- The task involves evaluating the derivative at \( x = 2 \), given in the last part of the text where \( f'(2) \) is to be computed.
