If you have a scientific calculator it really helps with simplifying numbers to the lowest term.
For this case we have the following expression:

Since the denominator is equal, then we can add the numerator.
We have then:

Adding similar terms we have:

Rewriting we have:

Doing common factor in the numerator we have:

Factoring the denominator we have:

Canceling similar terms we have:
Answer:
The simplest form of the expression has 7 in the numerator and m+4 in the denominator.
