Question

If (x - 1) is a factor of p(x) = kx²- 3x +k , then value of k is *


..3
..3/2
..2
..4​

Answer 1

Answer:

x=1

k(1²)-3(1)+k=0

k-3+k=0

2k=3

k=3/2

Follow me

Answer 2

Answer:

3/2

Step-by-step explanation:

(x-1) is a factor so putting x=1 in p(x) will give a 0.

p(x)=kx^2-3x+k

p(1)=k(1)-3(1)+k=0

0=k-3+k

3=2k

k=3/2
