What value of m will make this expression equal to 12.4?

9514 1404 393
Answer:
any value except -5.1
Step-by-step explanation:
The rational expression has a value of 1 for all values of m for which the expression is defined. (The numerator is equal to the denominator.) However, the expression is undefined for m = -5.1, so that value must be excluded from the domain.
