The expression a^2 + 10a + 16 can be written in factored form as (a + 8) (a + k), where k represents a number. What is the value of k?

Answer 1

To find the value of k, we need to identify the two numbers that can be multiplied to get 16 and added to get 10. These two numbers are 8 and 2. Therefore, the factored form of a^2 + 10a + 16 is (a + 8) (a + 2), and the value of k is 2.
