Answer:

x^2-x-12

Step-by-step explanation:

You can use the formula of FOIL, you go to each factor in the parenthesis and multiply by the other factors, the inside will first be x^2 then the middles will be 3x and -4x and the outside will be -12 then you simplify by combining like terms making the middle -x.
