Answer:

here is your answer and once try to solve it yourself

Answer 2

Correct question:

For what value of k, -4 is a zero of the polynomial x² - x - (2k + 2)

AnswEr:

value of k is 9.

SoluTion:

Given that, -4 is a zero of given polynomial,

put x = -4

=> (-4)² - (-4) - (2k+2) = 0

=> 16 + 4 - 2k - 2 = 0

=> 18 - 2k= 0

=> -2k = -18

=> k = 18/2

=> k = 9

Therefore, value of k is 9.
