a. +8 , -8
B. +8/3 , - 8/3
c. +3/8 , - 3/8
d. 0​

Answer 1

Answer:

B 8/3,-8/3

Step-by-step explanation:

Here a=16, b=6k, c=4

The formula for the equal roots is b^2-4ac=0

According to the formula

6k^2-4×16×4=0

36k^2-256=0

k^2=256/36

k^2= 64/9

k=√64/9

k = 8/3, -8/3

Answer 2

Answer:

+8/3, -8/3 is your answer
