Question

find the value of k, if x-1 is a factor of p(x). p(x)=kx²-½x+1​

Answer 1

Answer:

let p(x) be zero....

g(x)=x-1....

therefore0=x+1

x=-1...

therefor...

p(-1)=k(-1)^2 -1/2(-1)+1

0=k(-1)^2-1/2(-1)+1....shift the terms and find the answe for k

Answer 2

Answer:

-1/2

Step-by-step explanation:

x= 1

p(1)=k1sq- 1/2(1) +1

k-1/2+1=0

k+1/2=0

k= - 1/2
