Question

x-1 is a factor of 2x²-3kx+4, the value of k is​

Answer 1

Step-by-step explanation:

x-1=0

x=1

f(x) =2x^2-3kx+4

=2-3k+4

3k=6

thus, k=6

Answer 2

Answer:

ps like this and follow me

Step-by-step explanation:

x = -1

p(x) = 2x² -3kx +4

p(-1) = 2(-1)² - 3k(-1) + 4

= 2 + 3k +4

-3k = 6

k = 6/-3

Therefore,

k = -2
