Question

find value k if x+1 is a factor of 3x²-kx....Plz tell the correct answer only

Answer 1

Step-by-step explanation:

X+1=0

X=0-1

X=-1

3x^2 -kx=0

3×(-1)^2 -k×-1=0

3×1+k=0

3+k=0

k=0-3

k=-3

Answer 2

Answer:

-3.

Step-by-step explanation:

Given x+1

      or x-(-1) is a factor of f(x).

f(x) = $3x^{2}-kx$.

∴ 3(-1)²-k*-1=0.

or,3+k=0

or, k=-3.
