Basic Concept of Quadratic Equation
Quadratic equations are central to the Advanced Maths section of SSC CGL. Beyond simply finding roots via factorization, examiners love testing the conceptual properties of roots (sum, product, and nature) without requiring you to actually solve the equation. 1. Nature of Roots (Discriminant) For a standard quadratic equation ax2+bx+c=0ax2+bx+c=0, the Discriminant (D=b2−4ac)(D=b2−4ac) tells you exactly what kind of…
