Answer 2

Answer:

Correct option is

A

4/3

Given : One of the zeros of quadratic polynomial (k−1)x2+kx+1 is −3

To find : Value of k

Solution : As −3 is one of the zeros of quadratic polynomial (k−1)x2+kx+1

⇒ When we substitute −3 in the polynomial , we get 0

⟹(k−1)(−3)2+k(−3)+1=0

⟹9k−9−3k+1=0

⟹6k−8=0

or k=8/6=4/3
