Question

If x+1 is factor of polynomial 3x2 -kx find the value pf k

Answer 1

x= -1
3*2-k(-1)=0
-k(-1)=  -6
k = -6

Answer 2

Answer:

Step-by-step explanation:

First comfirm what ur question is?

Is 3x*2- k(x) or 3×2-kx

If it is 3x*2- k(x) then solution is

3(-1)*2 - k(- 1) =0

3(1)+k=0

K=0-3

K=o

And if ur Q. Is 3*2-kx

3*2-k=0

6+k=0

K=-6
