Question

find the value of k when (x-2) is a factor of 3x-2+k​

Answer 1

Answer:

as x+2 is a factor, remainder need to be zero

x+2=0

X=-2

substitute in the equation

3(-2)^2+k(-2)+6=0

3(4)-2k+6=0

2k=12+6

2k=18

k=9

Answer 2

Answer:

f (x) = 3x - 2 + k

If x - 2 is factor then,

» f (2) = 3 (2) - 2 + k

» 6 - 2 + k =0

» k = - 4

Therefore, the value of k is - 4.
