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
