Answer:
- The simplified expression is:

- The simplified expression is undefined for m=3
Explanation:
The given expression is:

The numerator can be siplified by using factorization and denominator will be simplified using the formula

So,

A fraction is undefined when the denominator is zero. In order to find the value of m on which the simplified fraction will be undefined we will put denominator equal to zero.
So,

Hence,
- The simplified expression is:

- The simplified expression is undefined for m=3
