this is the answer hope it helps u...

Answer 2

Answer:

The Value OF K = -3

Step-by-step explanation:

Given :-

-1 is one of the of quadratic equation ky - y - 4 =0

Then , p(x) = 0

p (-1) = 0

According To Question :-

P ( x ) = ky - y - 4

P ( -1 ) = k (-1) - (-1) - 4

0 = -k + 1 - 4

k = -3

Therefore , The Value of K = -3
