Question

if -4 is a zero of the polynomial x square minus x minus 2 + 2 k then find the value of k​

Answer 1

Answer:

K=-9

Step-by-step explanation:

polynomial is x^2 - x -2+2K = 0

if -4 is zero of the polynomial then it will satisfy the equation of polynomial

(-4)^2 - (-4) -2 +2K=0

16+4-2+2K=0

18 + 2K=0

2K= -18

K = -9
