P(x)=x^4-2x^3+kx-4 where k is an unknown integer
p(x)divided by (x-1) has a remainder of 0 what is the value of k?

k = 5.

Step-by-step explanation:

By the Factor Theorem if p(x) is divisible by x - 1 then p(1) = 0. So:

1^4 - 2*1^3 + k*1 - 4 = 0

1 - 2 + k - 4 = 0

k = 4 - 1 + 2

k = 5 (answer).

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
