Question

if x+1 is a factor of the polynomial 2x² + Kx when the value of K is​

Answer 1

Answer:

k=2

Step-by-step explanation:

X=-1

substituting the value

2(-1)²+k-1 = 0

2+-k = 0

-k=-2

k=2

Answer 2

Answer:

k=-2

Step-by-step explanation:

if, x+1=0

x=-1

2(-1)²+k(-1)=0

2(1)-k=0

2+k=0

k=-2
