Question

If one zero of a polynomial (k-1)x + kx +1 is -3 then find the value of k

Answer 1

Step-by-step explanation:

ANSWER

Given −3 is the zero of the polynomial (k−1)x

2

+kx+1

So −3 must satisfy the equation (k−1)x

2

+kx+1=0

⟹(k−1)(−3)

2

+k(−3)+1=0

⟹9(k−1)−3k+1=0

⟹9k−9−3k+1=0

⟹6k=8

⟹k=
