Answer:  2x^3-2x^2-13x+3

======================================================

Work Shown:

I'm assuming you meant to say (x - 3)(2x^2 + 4x - 1)

Let y = x-3

So,

(x - 3)(2x^2 + 4x - 1)\\\\y(2x^2 + 4x - 1)\\\\y2x^2 + y4x - y\\\\2x^2(y) + 4x(y) - (y)\\\\2x^2(x-3) + 4x(x-3) - (x-3)\\\\2x^3-6x^2 + 4x^2-12x - x+3\\\\2x^3-2x^2-13x+3\\\\

The basic idea is to use the distribution rule (line 3 and line 6) and then combine like terms.
