two negative integers have a sum of -18  and a product of 80 what are the integers?

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

Let the two integers be x and y. We have:

x + y = -18

xy = 80

From simple inspection, x = -10 and y = -8. You can also get this answer by substitution and using the quadratic formula.


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