100+ Most Repeated Quadratic Equations Questions for RRB PO, Know Tips To Solve Easily

Quadratic Equations For IBPS RRB PO 2025 Exam: The Quadratic equation is an important part of the IBPS RRB PO Quant section. Usually, quadratic equations contain 4-5 questions from this topic that appear in the prelims and mains stages, making it a high-scoring but tricky area that requires focused preparation. If you’re preparing for RRB PO 2025, in this article, we are providing 100+ most repeated questions for quadratic equations along with the tips and shortcut techniques to help you solve these questions faster and more accurately.

What are Quadratic Equations?

A Quadratic Equation is a polynomial equation of the form:

ax² + bx + c = 0

Here, a, b, and c are constants, x is the variable, and a ≠ 0. The solutions, or roots, of the equation represent the values of x that satisfy it. In the RRB PO exam, quadratic equation questions often involve comparing the roots of two equations (involving variables x and y) to determine their relationship, such as:

• x > y
• x < y
• x = y
• x ≥ y
• x ≤ y

A relationship cannot be established
