Question

12x3-8x2=4x factor

Answer 1

move 4x to the left side.
12x^3-8x^2-4x
GCF of all terms is 4x..
so 4x(3x^2 -2x -1)
3x^2 -3x +1x -1
3x(x-1)+1(x-1)

4x(3x+1)(x-1)

Answer 2

Does this make sense?

Answer 3

4x(3x+1)(x+1)?

Answer 4

yes

Answer 5

12x^3-8x^2-4x=0
4x(3x^2-2x-1)=0
4x=0 or (3x^2-2x-1)=0
x=0 or 3x^2 -3x +1x -1=0
x=0 or 3x(x-1)+1(x-1)=0
x=0 or (3x+1)=0 or (x-1)=0
x=0 or x=-1/3 or x=1

so there can be three possible values of x=0,1,-1/3
