Question

find the value of k, if x-2 is a factor of x²-3kx+2​

Answer 1

Answer:

k=-12

Explanation:

= x-2

x=2

putting value of x

(2)²-3k(2)+2=0

4-6k+2=0

6-6k=0

6k=-6

k=-6-6

k=-12

Answer 2

Answer:

k = 1

f(x) = x²-3kx+2

x-2 is a factor of f(x),

x-2 = 0

x = 2

Hence,

f(2) = 2²-3k(2)+2 = 0

4-6k+2 = 0

-6k = -6

k = -6/-6

k = 1
