For an integer , x the inequality
has no real solutions in n. Find the number of different possible values of .x^2+nx+15<0
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:
