Thank you for the opportunity to help you with your question!

since x^2+1>0, and (x-8)^2 >=0, 

(X-8)^2 (x^2+1)>=0, 

thus the inequality (X-8)^2 (x^2+1)<0 has no solution,  thus the solution set is empty set

Please let me know if you need any clarification. I'm always happy to answer your questions.
