The answer would be C. 
If you do -5.5 + 2.5 over 6.1 - 3.1 it would be -3 over 3 which is equal to -1. 
You could also do -2.5 + 5.5 over 3.1 - 6.1. It would be 3 over -3 which is also equal to -1.

Answer:
Factoring the expression  completely we get
 completely we get 
Step-by-step explanation:
We need to factor the expression  completely
 completely
We need to find common terms in the expression.
Looking at the expression, we get  is common in both terms, so we can write:
 is common in both terms, so we can write:

So, taking out the common expression we get: 
Now, we can factor the term (1+x^3) or we can write (x^3+1) by using formula:

So, we get:

Therefor factoring the expression  completely we get
 completely we get
