Question

Find the value of k , if -1 is a zero of the polynomial p(x)= kx^2 -4x +k. *​

Answer 1

Answer:

k = 0

Step-by-step explanation:

-1 is a zero of polynomial p(x)

Then, p(-1) = 0

So, k(0)^2 - 4(0) + k = 0

implies 0 - 0 + k = 0

Thus, k = 0 (Answer)

Answer 2

Step-by-step explanation:

-1 is zero polynomial p(x)

Then, P (-1)=0

so, k(0)² - 4(0) + k=0

it implies 0-0+k=0

Answer:K=0
