Question

f (x+1)is a factor of polynomial f(x)= kx +2x² +1then k​

Answer 1

Step-by-step explanation:

x+1=0

x=-1

Putting the value of x

f(-1)=k(-1)+2(-1)^2+1

-k+2+1=0

-k+3=0

-k=-3

K=3

Answer 2

Answer:

x+1=0 then x=-1

substitute values

k(-1)+2(-1)^2+1

then -k+2+1=0

-k+3=0

-k=-3

then k=3

hope this answer will help you
