Homework Help: Algebra

Posted by Aria on Tuesday, August 2, 2011 at 1:58am.

I am stumped by these two LCM questions for some reason.

Find The LCM for
#1
2(R-7) and 14(R-7)

#2
(1+4r), (1-16r^2), and (1-4r)

It seems like #1 is already at the LCM
and #2 would be (1+4r)(1-4r)
Am I even vaguely correct?
Thanks for your help.
