You can put this solution on YOUR website!
The expression is undefined if the bottom of denominator is 0 as you can't /0.
So, we want to see when the bottom is 0.
...
2m%5E2%2Bm-3=0
2m%5E2%2B3m-2m-3=0
m%282m%2B3%29-%282m%2B3%29=0
%28m-1%29%282m%2B3%29=0
m-1=0 or 2m%2B3=0
m=1 or m=-3%2F2
Therefore, if m is equal to 1 or -3/2 than the expression is undefined.
