We solve this step-by-step using the concept of equal roots in a quadratic equation, i.e.,
Discriminant (D) = 0 for equal roots.

This is an important question for DSC aspirants and a must-practice problem under Quadratic Equations.

Topics Covered:

Discriminant method

Quadratic Equation basics

Algebraic manipulation
