possible values of b: $16,-16,8,-8$
If the trinomial $ax^{2}+bx+c$ can be factored, it will be in the form $(x+n)(x+m)$, where the product of integers n and m is $c$ their sum is $b.$ c is positive, both factors have the same sign. $\left[\begin{array}{ccc} \text{pairs of factors} & \text{sum = b} & \\ 1,15 & 16 & \\ -1,-15 & -16 & \\ 3, 5 & 8 & \\ -3,-5 & -8 & \end{array}\right]$ possible values of b: $16,-16,8,-8$
