Question

find the value of k if x-3 is a factor of polynomial kx2 -x+1​

Answer 1

Step-by-step explanation:

Find the value of k,if X-1 is a factor of polynomial P (x)=kx²-3xk

solution

Give polynomial=

p(x)=Kx²-3x+k

x-1=0 (Given)

x=+1

Polynomia p(x)=kx²-3x+k

p(1)=k(1)²)-3(1)+k

k×1-3+k=0

k+3+k=0

2k-3=0

2k=3

k=3/2

THE REQUIRED VALUE OF K=3/2

Answer 2

Kx2-x+1=0. x-3=0

K(3)-(3)+1=0. x=3

K0+1=0

K+1=0
K=0-1
K=-1
