Simplify Rational Expressions m-3/3-m
Let us rewrite 3-m as (-1)(-3+m)
= (m-3)/ (-1)(m-3)
= (-1)*1= -1
To simplify m-3/3-m
m-3/3-m= m-1-m = -1 .Where m and -3/3 and -m are treated as 3 distinct terms and each can still be rational expression m/1 - 3/3 - m/1. Also following the priority rule of operations . To avoid confusion we should use brackets properly.
(m-3)/(3-m) and m-3/3-m are different operation but value is -1 only.
