Question 982107
Analyze each of the rational expression first, and discuss their characteristics.  You would undoubtedly use the needed terminology in the discussion.  TRY THAT!  Just as said, analyze each expression and DISCUSS what inputs are and are not acceptable, and any products and factors which occur, and anything else to characterize inputs and outputs of the expressions.

Just guessing but your expression might really be
(5m^2 + m)/(7m) and (12y -15)/(25y^2 -4).
