Question

Find k if (-4) is the remainder when x^4 + 2x^3 - 3x^2 + kx + 12 is divided by x + 2
please answer the question

Answer 1

Step-by-step explanation: It is not possible as degree of r(x) is never equal to degree of g(x). The power of remainder is always less than that of the divisor.

Answer 2

Answer:

k= 8

Step-by-step explanation:

Putting x = -2 in the equation we get,

-2^4 +2(-2)^3 + 3(-2)^2 + k(-2) = -4

16 - 16 + 12 - 2k = -4

-2k = -4 - 12

-2k = -16

k = -16/ -2

k= 8
