Q:
# Solve for x. Enter your answer in interval notation using grouping symbols x^2+2x<15

Accepted Solution

A:

Answer:The answer to your question is (-5, 3)Step-by-step explanation:Process1.- 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 < 3The solutions crosses in the interval (-5, 3) so this is the solution
