Question

If (x-2) is a factor of P(x) = x² + 2kx + 8 , then k= ?

Answer 1

Step-by-step explanation:

i hope it helps you plz thank my answer

Answer 2

Answer:

Zero of the polynomial x =2

g(x) =2

p(x) = x² + 2kx + 8

(2)² + 2k X 2 + 8 = 0

4 + 4k + 8 = 0

12 + 4k = 0

4k = -12

K = - 12/4

k = - 3
