Answer:
Step-by-step explanation:
✸Given:-
-3 is a root of Quadratic Equation (k-1)x² - kx + 1.
✸To Find:-
The Value of k .
✸Solution:-
p(x)=(k-1)x² - kx + 1=0
Now, it is given that (-3) is a root of this Quadratic Equation.
∴ Putting x=3:-
⇒p(-3)=(k-1)(-3)² - k(-3) + 1=0
⇒(k-1)(9)+3k+1=0
⇒9k-9+3k+1=0
⇒12k=8
