find the value of k so that the remainder of
(-kx^4 - 146x^2 + 32)divided by (x-4)is 0
A)37/4
B)9
C)-37/4
D)-9
----------------------------
Using synthetic division:
4)....-k....0....-146....0....32
.........-k...-4k.....-146-16k....|32+4(-146-16k)
------------------
Remainder: 32 - 584 - 64k = 0
64k = -552
k = -(69/8)
