Answer:
(5s + 8) is the missing factor.
Explanation:
The given expression is 5s² + 23s + 24
We have to convert the given expression into the factored form.
One factor of the expression has been given as (x + 3)
5s² + 23s + 24 = 5s²+ 15s + 8s + 24
= 5s(s + 3) + 8(s + 3)
= (5s + 8)(s + 3)
So the factors of the expression will be (s + 3) and (5s + 8)
Therefore, the missing factor of the given expression is (5s + 8).
