first of all, since there is no x-term, you would have to create space for it by writing 0x. then,x divides 3x2 and leaves a remainder of 3x which you right at the top on the 0x. the 3x multiplies the x+2.

you would then subtract the final from the initial. write your final answer and write the next number down beside your result. x divides -6x and leaves a remainder of -6 which you write at the top. the -6 multiplies the x+2 to give you -6x-12 .
