Answer:
b. 5
Step-by-step explanation:
For the trinomial to be factorable using integers, the value of b will be the difference of two factors of 24.
24 = 1×24 = 2×12 = 3×8 = 4×6
Differences of these factors are 23, 10, 5, 2. Of these, only 5 is listed as a choice.
b = 5 will make the expression factorable.
