Question

If (x - 2) is a factor of the polynomial x ² - x + 2K then find the value of K
​

Answer 1

Answer:

k=-1

Step-by-step explanation:

x-2 = 0

x=2

x^2-x+2k=0

2^2-2+2k=0

4-2+2k=0

2+2k=0

2k=-2

k=-2/2

k=-1

Answer 2

x - 2 = 0
x = 2

p(x) = x² - x + 2k
p(2) = (2)² - 2 + 2k
p(2) = 4 - 2 + 2k
p(2) = 2 + 2k

2 + 2k = 0
2k = - 2
k = -2/2
k = - 1
