Do you know how to set up the coefficients of P(x) for synthetic division?

directrix · Answer

Nobody is looking. It's okay to write something. I just need to know where to begin.

directrix · Answer

P(x) =  1 x^3  + 3 x ^2 + 0x + 4
So, the coefficients for the synthetic division will be:  1  3  0  4

Note that if there is a gap in the powers of x as in this problem (there's no shown x term) then you must account for its coefficient of 0 as in 0x.
