Question

Answer 1

4x^3 -2x^2 -12x

4x^3 -2x^2 -12x

x is common in all.
Factor it out first.

x(4x^2 -2x - 12)
Next to simplify you can factor out 2 as well.

2x(2x^2 -x - 6)

now factor the thing inseide the brackers.

Find 2 terms to whom when we multiply we get -12 and when we add we get -1.

Answer 2

-4 and +3.

Answer 3

2x(2x^2 -x - 6)

2x(2x^2 -4x + 3x - 6)

Now make pairs.

2x[2x(x-2) +3(x-2)]

Finally:

2x[(2x+3)(x-2)]

Rewrite them as:

2x(2x+3)(x-2)

Completely factored^
