Question

I. Find the value of K, it x-1 is a factor
of 4x3 + 3x² - 4x + k.
​

Answer 1

Answer:X - 1 is a factor of 4x^3 + 3x^2 -4x +k

then x=1 is one root of 4x^3 + 3x^2 -4x +k

put x= 1

4x^3 +3x^2 -4x +k = 0

=> 4 (1)^3 +3 (1)^2-4 (1) +k =0

=> 4 + 3 - 4 + k = 0

=> k = -3

Answer 2

Step-by-step explanation:

if x-1 Is a factor then x=1

putting x=1 in

4x³+3x²-4x+k

4+3-4+k=0

3+k=0

k=-3
