Question

if x+1 is factor of the polynomial 2x^2+kx then value of k is ​

Answer 1

Answer:

X+1=0

so, X=-1 ----------------1

applying 1 on the polynomial

2(-1)² + k(-1) = 0

2 + (-k) = 0

-k = -2

so,. k=2

Hope you got it

Answer 2

Answer:

k=2

Step-by-step explanation:

2x² / x = kx / 1

2x = kx

When we cut x, we get

2 = k

Therefore, k=2.
