Step-by-step worked solutions to Quadratic Equations Exercise 2.3 (National Book Foundation, Unit 02) for FBISE Class 10 and O-Level students. Covers the discriminant b² − 4ac and what it says about the nature of roots — real/rational, real/irrational, equal (repeated) and imaginary — plus finding unknown constants for equal roots and proving root properties. All 10 questions fully worked with checks. Every step shown — ideal for exam prep and self-study.
