To factor the quadratic expression \( x^2 + 13x + 36 \), we are looking for two numbers that multiply to 36 (the constant term) and add up to 13 (the coefficient of the linear term).

The numbers that meet these criteria are 9 and 4 because:

- \( 9 \times 4 = 36 \)
- \( 9 + 4 = 13 \)

Therefore, we can factor the expression as follows:

\[
x^2 + 13x + 36 = (x + 9)(x + 4)
\]

So, the complete factored expression is:

\[
x^2 + 13x + 36 = (x + 9)(x + 4)
\]

In the context of your original question, the correct completion would be:

\( x^2 + 13x + 36 = (x + 9)(x + 4) \)
