Answer:

 \huge \bigstar \:   \huge \boxed{k =  \frac{4}{3}  } \: \bigstar

Step-by-step explanation:

Given :–

  • One of the zero of the Quadratic Polynomial (k-1)x²+kx+1 is -3.

To Find :–

  • The Value of k.

Solution :–

p(x)=(k-1)x²+kx+1=0

=> Put x=(-3) in this Quadratic Polynomial:

→ p(-3)=(k-1)(-3)²+k(-3)+1=0

→ (k-1)(9)-3k+1=0

→ 9k-9-3k+1=0

→ 6k-8=0

→ 6k=8

 \implies k =  \frac{8}{6}

 \star \:  \boxed{k =  \frac{4}{3}  } \: \star
