Question

if x³ +6x²+4x+ k is exactly divisible by x+2, Then k​

Answer 1

Step-by-step explanation:

step 1: divide the given p(x) with the given value of g(x) at last you will get k=-8

Answer 2

Answer:

The value of k is -40

Step-by-step explanation:

If x³ +6x²+4x+k is exactly divisible by x+2:

x+2=0

x=-2 should make the polynomial value 0.

Substituting the value of x,

(2*2*2) + (6*2*2) + (4*2) +k = 0

8 + 24 + 8 +k = 0

40 + k = 0

k = -40

Hence, k = -40
