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.
For additional review (including worked examples), try some online lessons on adding rational expressions (that is, adding polynomial fractions).
