To factor the quadratic equation \(x^2 + 10x + 16 = 0\), we need to find two numbers that multiply to \(16\) (the constant term) and add up to \(10\) (the coefficient of the linear term).
The numbers that satisfy these conditions are \(2\) and \(8\), since:
- \(2 \times 8 = 16\)
- \(2 + 8 = 10\)
Thus, the factored form of the equation is:
\[
(x + 2)(x + 8) = 0
\]
So, the answer is:
\[
(x + (2))(x + (8)) = 0
\]
If you need to enter the numbers in the format requested, you would write:
\((x + (2))(x + (8)) = 0\)
