Question

 If kx³+8x²-4x+10 is divided by (x+1) leavs the remainder is -3 then the value of k is ? *​

Answer 1

Answer:

x+1=0

x=-1

k(-1)³+8(-1)²-4(-1)+10

-k+8+4+10

-k+12+10

k=22 OK friend

Answer 2

Answer:25.

Step-by-step explanation:

x+1 = 0.

x = -1.

Substituting x as -1,

k(-1)³+8(-1)²-4(-1)+10 = -3.

-k+8+4+10 = -3.

-k = -3-22

-k = -25

k = 25.
