Answer 2

The value of k is $\frac{4}{3}$.

Step-by-step explanation:

The polynomial is:

$(k-1)x^{2}+kx+1=0$

One of the roots of the polynomial is -3.

Then x = -3 will satisfy the equation.

Compute the value of k as follows:

$(k-1)x^{2}+kx+1=0$

$(k-1)(-3)^{2}+k(-3)+1=0$

$9(k-1)-3k+1=0$

$9k-9-3k+1=0\\6k-8=0$

$k=\frac{8}{6}=\frac{4}{3}$

Thus, the value of k is $\frac{4}{3}$.
