Question

if X + 1 is factor of polynomial 2 X square + kx then the value of k is​

Answer 1

Answer:

I gave the step by step explaination.

Step-by-step explanation:

Let the given polynomial be p(x)=2x^2+kx

according to factor theorum, If (x+1) is a factor of p(x), Then p(-1)=0

p(+1)=2x^2+kx=0

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

2+k=0

k=-2

Therefor K will be equal to -2
