.
According to irrational root theorem if 
is root of a polynomial P(x), then 
is also a root of polynomial P(x).

Answer:
-15
Step-by-step explanation:
1/-13
The reciprocal is
Because of the law of indices,
We'll have 
= -13.
-1/2
The reciprocal is
1 ÷ -1/2
Because of the law of indices,
We'll have 
= -2
Therefore, the sum would be -13 + (-2) which would be equals to -15.
