weird way to ask you to factor 
$$2x^2-29x+12=(x+4)(\text{something})$$

$$2x^3-29x+12=(x+4)(\text{something})$$

anonymous · Answer

you can figure it out either by dividing or by thinking

anonymous · Answer

Divide as if you were doing long division (multiply to fit the first value, then subtract, then do the same for the next values, etc.)
