Question

if -1 is a zero of the polynomial , p(x) =

2 + 8 + , then find the value

of k ?​

Answer 1

Answer:

Given :

P(x) = x²+11x+k

To Find:

Value of k

Solution :

Given that -4 is the zero of polynomial p(x)

Putting x = -4

p(x) = x²+11x+k

p(-4) = (-4)²+11(-4)+k

16-44+k = 0

-28+k = 0

k = 28
