If you would like to find the value of b, you can do this using the following steps:

x^2 + bx + 16 = 0
x = 4

4^2 + 4 * b + 16 = 0
16 + 4 * b + 16 = 0
4 * b = - 32    /4
b = - 32/4
b = - 8

The correct result would be b = - 8.

Answer:

answer B=-8

Step-by-step explanation:

x^2 + bx + 16 = 0

x = 4

4^2 + 4 * b + 16 = 0

16 + 4 * b + 16 = 0

4 * b = - 32    /4

b = - 32/4

b = - 8
