Question

P(x) = x^4 – 2x^3+ kx – 4 where k is an unknown integer.

Answer 1

Answer:

k = 4

Step-by-step explanation:

Given,

$P(x)=x^{4} -2x^{3} +kx-4$

when , P(x) is divided by (x - 1) , the remainder = 0

⇒ $P(x) = (x-1)(x^{3} -x^{2} -x+4)$

hence, k = 4

Answer 2

Answer:

k does not equal 4, it equals 5
