Introduction:
In this problem, we are given a polynomial p(x) and we need to find the value of k such that -4 is a zero of p(x).

Given:
p(x) = x^2 + 11x + k
Zero of p(x) = -4

Solution:

We know that if -4 is a zero of p(x), then p(-4) = 0.

Let's substitute -4 in the given polynomial to get:

p(-4) = (-4)^2 + 11(-4) + k = 16 - 44 + k = k - 28

As we know that p(-4) = 0, we can write:

k - 28 = 0

Therefore, k = 28.

Conclusion:
Hence, we have found that k = 28, such that -4 is a zero of the given polynomial p(x) = x^2 + 11x + k.
