-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.

Since the denominator is a monomial, we divide each term of the trinomial in the numerator by the denominator.

, because 3/-3 = 1 and x³/x = x².

; 9/-3 = -3 and x²/x = x.

; -6/-3 = 2 and x/x = 1, so we have 2*1 = 2.
Together this gives us
