35b^3c**

find the LCD of the pair of expressions
3m/m+n ; 3n/m-n

(m+n)(m-n)
2m
2mn
(m-n)^2**

Answer 1

#1, no, your denominators are 2 and x^2, so what do you need?
#2, correct
#3, your denominators are m+n and m-2
so will need (m+n)(m-n) , which would be m^2 - n^2, NOT (m-n)^2

Hope you didn't just guess at the answers.
