im not doing you fuckin' homework for you! I passed math 30 a while ago. But as for helping you. OK. Just multiply out all the brackets then group the alike variables then simplify. Sound easy? well it is.

3x[2(2x-y)-(x-1)(y+4)-(4-xy)]
3x(4x-2y-x+1+y+4-4+xy)
12x2-6xy-3x2+3x+3xy+12x-12x+3x2y
9x2-3xy+6x+2y
this is what i got and i pretty much show all the steps, check it if ya want.
Thx
this is not rocket science....
didn't you learn that multiply and division
comes before addition and subtraction
3x[4x-2y-(xy-1y+4x-4)-(4-xy)] =
-3xy
