The negative sign in the multiplication calculation can be moved to everywhere. So the number should be -8.
Answer:
<h3>c =2</h3>
Step-by-step explanation:
For the polynomial to be divisible by x-4, hence x = 4
Given
p(x) = cx^3-15x -68
p(4) = c4^3-15(4)-68
p(4) = 64c-128
If p(4) = 0
0= 64c - 128
64c = 128
c = 128/64
c = 2
hence the value of c is 2
