How do I factor 4 term polynomial?

[jester0608]

Hi guys, I'm not entirely good with factoring so I was wondering if any of you can show me how I would go about factoring this polynomial:
(With necessary steps if you can Please and thanks!)

36mx + 10y - 24x - 15my

Hi jester0608! http://img96.imageshack.us/img96/5725/red5e5etimes5e5e45e5e25.gif

Here's a start, see whether you can complete the last line, then figure what comes next.

36mx + 10y - 24x - 15my
=36mx - 24x - 15my + 10y
=12*3mx - 12*2x - 5*3my + 5*2y
=12x*3m - 12x*2 - ...

BTW, this looks like homework, so should be in the homework help section.
