Answer:
Simplified expression:
Restrictions:
Step-by-step explanation:
The expression is:
We can simplify the denominator of the first fraction:
Then we can simplify the denominator of the second fraction:
The least common multiple of the denominators is , therefore we have:
The simplified expression is:
The restrictions are the values of m that makes the denominator zero, so we calculate them using a 'not equal' sign:
