Answer:
x+1
DOMAIN: x
-5
Explanation:
We can factor
+6x+5 as (x+1)(x+5) since this expands to
+5*x+1*x+5*1, which is
+6x+5.
Now, we have:
We can cancel out x+5, because this expression is the same as (x+1)*
, which is (x+1).
HOWEVER, the denominator cannot be equal to zero because that will make the expression undefined (you can't divide by zero). So, since x+5
0, x
-5.
