Question

If (x+1) is a factor of polynomial (2x²+ax) then k=?​

Answer 1

Answer:

Hence , the value of k is 2.

Answer 2

I think you typed question wrong

Actually, the question should be in this(2x²+kx)form

Let, p(x)=2x²+kx

x+1 is factor of p(x) then ,p(-1)=0

Therefore,2(-1)²+k(-1)=0

2-k=0

-k=-2

hence,k= 2
