The value of k for which x - 1 is a factor of \( \Large 4x^{3} + 3x^{2} - 4x + k \) is

A) 3
B) 1
C) -2
D) -3

Correct Answer:




D) -3

Description for Correct answer:
(x - 1) is a factor of \( \Large 4x^{3} + 3x^{2} - 4x + k \)

On putting x = 1

\( \Large 4(1)^{3} + 3(1)^{2} - 4(1) + k = 0 \)

=> 4 + 3 - 4 + k = 0

=> k = - 3
