Use the FOIL method (First, Outer, Inner, Last) and multiply the terms within the parenthesis.
You should end up with: 3x^2-13x+4

Remember FOIL
First, Outer, Inner, Last
3x^2 - 12x -x + 4
3x^2 - 13x + 4

Use FOIL first outer inner last
3x^2 - 12x - x + 4
3x^2 -13x +4

(3x-1)(x-4) times them together
3x^2-12x-x+4 add 'em up
3x^2-13x+4
hopefully that's right.

Hello.......this is the simplified expression......there is no way to simplify it anymore
If you want it to be expanded...the answer would be 3X^2-13X+4
