Hi,
Need a little help with this. We are simplifying the following, but the solution is pretty lengthy and messy because of the enormous number of factors. I was thinking that may be I am missing seeing a pattern (some series or something). Is grunt work the only way to solve this or is there a pattern that can simplify the whole process?
My daughter was trying to solve this, but ended up with the mess and then I got the same mess, but I thought there may be an easy way to simplify this that I may be missing.
((bc)/((ab)(ac))) + ((ca)/((bc)(ba))) + ((ab)/((ca)(cb))) + (2/(ba))  (2/(ca))
of course, I took all the factors in the denominator and then started multiplying the numerator with the remaining factors to end up with a mess.
Your help is appreciated.
