Question

6. Find the the value of Kif x-2 is a factor of the polynomial x - 2kx + kr - 1​

Answer 1

Step-by-step explanation:

0 = 2 - 4k + 2k -1………(Putting values of x as 2)

0 = 1 - 2k

2k = 1

k = 1 / 2

hope this helps...

Answer 2

Answer:

If -2 is the factor of the equation then the zero of -2 is 2

then,

p(x)= x-2kx+k-1

p(2)= 2-2k(2)+k-1=0

⇒2-4k+k-1=0

⇒-4k+k=-1

⇒k+k=-1/-4=1/4

⇒2k=1/4

⇒k=1/4 × 2

=1/2
