Question

for what value of k is the polynomial 2x4+3x3+2kx2+3x+6 exactly divisible by (x+2)?

Answer 1

X + 2 equals to X -2 now where there is X we will put -2 and then if it is exactly divisible then answer will come 0 if it is there then it is correct 8+9+-8+-6+6=9 so X + 2 is not exactly divisible by PX which is are 2 into 4 + 3 into 3 + 2 X into 2 + 3 X + 6
