The solution set for the inequation |x − 2| + |x + 3| < 2 is _______.
Explanation:
Here, the critical points are x = -3 and 2
Case 1: x > 2 ∴ x – 2 + x + 3 < 2 ⇒ 2x < 1 ⇒ x < ½ (this contradicts our assumption that x > 2) ∴ No solution
Case 2: -3 < x < 2 ∴ -(x - 2) + x + 3 < 2 ⇒ 5 < 2 (not true) ∴ No solution
Case 3: x < -3 ∴ -(x - 2) – (x + 3) < 2 ⇒ -2x < 3 ⇒ x > -3/2 (this contradicts our assumption that x < -3/2) ∴ No solution
∴ There is no real value of x for which |x − 2| + |x + 3| < 2.
Hence, option (d).
