what multiplied together = +15    added together=n

 

                           n=

3  5                      8

-3  -5                   -8

15  1                   16

-15  -1                 -16

 

Plug in these values for n and graph.....the only values of the quadratic that I see are   (-15,-1) U (1,15)

 

(I am not sure of this answer)

 

Here is the graph:
