Question

find the value of k if x-1 is a factor of x²-2x+k​

Answer 1

Answer:

k=1

Step-by-step explanation:

Let p(x) = x² - 2x + k.

Then,

As ( x - 1 ) Is a factor

p(1) = 0.

Therefore the value of k is 1.

Answer 2

Answer:

below the answer

Step-by-step explanation:

According to factor theorem, when f(x) is divided by (x−1),f(1)=0

f(x)=x

2

+2x−k

⟹f(1)=1

2

+2(1)−k=0

⟹3−k=0

⟹k=3
