Answer 2

Question :

find the value of K

Given:

(x - 1 )

x = 1

so the value of x = 1

Given equation :

4x3 + 3x2 -4x + k

Solution :

4x3 + 3x2 - 4x + k

put the value of x in equation that is 1

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

4 + 3 - 4 + k = 0

7 - 4 + k = 0

3 + k = 0

k = -3

so the value of K is -3

hope it's help
