Question 968011:  simplify expression and state the excluded values of the variables
 
3 m^2 n^3 / (36 m n^3 - 12 m^2 n^2)
 
simplified I get   m n / 12 n - 4 m
 
but can't find the excluded
 
should it be 3n, 0, 0 ?

You can  put this solution on YOUR website! simplify expression and state the excluded values of the variables  
3 m^2 n^3 / (36 m n^3 - 12 m^2 n^2)  
simplified I get m n / 12 n - 4 m  
but can't find the excluded  
should it be 3n, 0, 0 ? 
-------------------------- 
3 m^2 n^3 / (36 m n^3 - 12 m^2 n^2) 
------ 
= [3m^2n^3]/[12mn^2(3n-m)] 
------ 
= [m*n]/[4(3n-m)] 
======= 
Excluded variable values:: m = 0, n = 0, m = 3n
