Question

0.18. If (x - 3) is a factor of x - kx-2, then the value of k is
(A) 5/3 (B) 7/3 (C) 2/3 (D) 1/3​

Answer 1

Answer:

put x=3

then 3-3x-2=0

1-3x=0

3x=1

x=1/3

Answer 2

Answer:

k =1/3

Step-by-step explanation:

Since (x-3) is a factor of x-kx-2

So x-3 =0

x= 3

Put this value of x in given equation

x - kx -2 =0

3- k(3)-2 =0

3-3k-2 =0

1 = 3k

1/3 = k

k = 1/3
