To factor the trinomial \(x^2 + 10x + 24\), we need to find two numbers that multiply to 24 (the constant term) and add up to 10 (the coefficient of the linear term).
The numbers that satisfy these conditions are 4 and 6 because:
- \(4 \times 6 = 24\)
- \(4 + 6 = 10\)
Therefore, we can factor the trinomial as follows:
\[ x^2 + 10x + 24 = (x + 4)(x + 6) \]
Among the given choices, the equivalent expression is:
\((x + 4)(x + 6)\)
So, the answer is: \((x + 4)(x + 6)\)
