Need help. I had this stuff the other day but seem to have forgotten and need review. Here's the problem...
5 over 4xy + 5 over 12yz
I think it's because it's three variables that I don't even know where to start. Most of my other problems like this have been trinomials with 1 or 2 variables.
So it'd end up being 60yz + 20xy over 48xyz?
That's what I got following what you showed me, but I wasn't sure if there was any factoring involved with something like that. The steps my book uses seem a lot more complicated and talks about finding the least common denominator and such.
