Final answer:
The given expression -17/(x^2+1) cannot be simplified further since x^2+1 is a sum of squares and cannot be factored.
Step-by-step explanation:
The given expression is -17/(x^2+1).
To simplify this expression, we need to factor the denominator, which is x^2+1. Since x^2+1 is a sum of squares, it cannot be factored further. Therefore, the expression cannot be simplified any further.
So, the simplified form of the given expression is -17/(x^2+1).
