# CAT Practice : Inequalities

You are here: Home  CAT Questionbank   CAT Quant  Algebra: Inequalities  Question 8
The product of two terms are negative when one of them is negative, and the other positive. If both are negative or positive, the product will be positive. When will these two terms be seperately negative?

Q.8: (|x| - 2) (x + 5) < 0. What is the range of values x can take?

The range is (-∞, -5) or (-2, 2)

## Detailed Solution

This can be true in two scenarios.

Scenario I: (|x| - 2) < 0 and (x + 5) > 0
Or |x| < 2 and x > -5.This gives us the range (-2, 2)

Scenario II: (|x| - 2) > 0 and (x + 5) < 0
Or |x| > 2 and x < -5. This gives us the range (-∞, -5)

So, the overall range is (-∞, -5) or (-2, 2)

Correct Answer: (-∞, -5) or (-2, 2)
