Question

The value of k, if (x – 1) is a factor of 4x3 + 3x2 – 4x + k, is
(a) 1
(b) 2
(c) –3
(d) 3

Answer 1

Answer:

IF (x-1) is the factor of 4x³+3x²-4x+k then the value of x satisfied the equation

x-1=0

x=1

put the value of x in equation

4(1)³+3(1)²-4(1)+k=0

4+3-4+k=0

3+k=0

k= -3 ANSWER
