Question

find k if x is a factor of 3xsquare +kx+6​

Answer 1

Step-by-step explanation:

If (x+3) is a factor of 3x²+kx+6 = f(x) then f(-3)=0 According to factor theorem. k = 11 .

Answer 2

Step-by-step explanation:

3x2 + x = 0

Take x as common from LHS

Factors of x

=x (3x + 1) = 0 %

3D = (x) (3x +1) = 0

Therefore,

x = 0 Factor of 3x+1 > 3x +1=0 > 3x = -1 >x = -1/3

Therefore, The requred factors are x and 3x+1.
