Question

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

Answer 1

Answer:

Here's your answer

$2 ({ - 1}^{2} ) + k( - 1) = 0 \\ \\ 2 - k = 0 \\ \\ - k = - 2 \\ \\ k = 2$

Hope it helps ❤❗

Answer 2

Answer:

k=2

Step-by-step explanation:

if x+1 is a factor,

==> x+1=0

==>x=(-1).

Substituting into the polynomial, we get:

==>2(-1)^2+k(-1)=0

==>2(1)+(-k)=0

==>2-k=0

==>-k=-2

==>k=2

Final answer we get is k=2.
