Answer 1

Answer:

k = 9

Step-by-step explanation:

p(x) = x² - x - (2k + 2)

p(-4) = (-4)² - (-4) - (2k + 2)

p(-4) = 16 + 4 - (2k + 2)

p(-4) = 20 - (2k + 2)

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

Therefore , p(-4) = 0

ATQ ; p (-4) = 0

→ 20 - (2k + 2) = 0

→ 20 = 2k + 2

→ 20 - 2 = 2k

→ 18 = 2k

→ 18/2 = k

→ 9 = k

→ k = 9

HOPE IT HELPS YOU DEAR

THANKS !

Answer 2

Answer:

k=9

Step-by-step explanation:

let the other zero be m

-4+m=-(-1)/1

-4+m=1

m=5

-4×5=-(2k+2)/1

20=2k+2

18=2k

k=9
