Answer:
The answer to your question is (-5, 3)
Step-by-step explanation:
Process
1.- Factor the inequality
x² + 2x < 15
x² + 2x - 15 < 0
(x + 5)(x - 3) < 0
2.- Find x,
- the inequality must be negative, so x + 5 < 0 and x - 3 > 0
x + 5 < 0 x - 3 > 0
x < -5 x > 3 the solutions do not crosses
- the inequality must be negative, so x + 5 > 0 and x - 3 < 0
x > -5 x < 3
The solutions crosses in the interval (-5, 3) so this is the solution
