What are two numbers that equal 15 and -8? THIS IS 27 POINTS thank you!

Answer:-3 and -5Step-by-step explanation:Why it is, is you are putting your equation into two separate parts. (r-__)(r-__). That will give you the r^2. You then have to think of the -8 and the 15. When you times -3 and -5 together you get 15, and if you add it together you get -8. So it will be (r-3)(r-5). How this is, is you will do FOIL. F=FRONT. You do the r's to get r^2. O=OUTER. You add the r and the -5 (which are the outer) to get -5. I=INNER. You add the other r and the -3 (which are the inner) to get -3.L=LAST. You times the -3 and the -5 (which are last) to get 15. You then put it together to get r^2-8r+15=0. So your answers are -3 and -5.
