Question

if (x-2) is a factor of x 2 - kx + 4, then the value of k ​

Answer 1

Answer:

x-2=0

x=2

4-4k+4=0

8-4k=0

-4k=-8

k=2

hope it helps and please mark me as brain list please as it takes a lot of effort to type question please it's your request please mark me as brain list

Answer 2

Answer:

(x-2) is the factor of the quadratic equation

so it will satisfy in the equation

x-2=0

x=2

so put x=2 in the equation x^2-kx+4=0

2^2 -2k+4=0

4-2k+4=0

2k=8

k=8/2

k=4
