Types of Quadratic Equation Questions
- Variable Comparison Type:
You are given two equations, one in x and another in y. You must compare their roots and select the correct relationship:- x > y
- x < y
- x ≥ y
- x ≤ y
- x = y or no relation
- Simple Root Finding:
Some sets directly ask for the roots of a quadratic equation. These are usually easier and can be solved through factorisation or the formula method. - Mixed Arithmetic Quadratic Problems:
In RRB PO Mains, quadratic equations can appear in caselets or arithmetic-based data interpretation sets, often combined with ratio, average, or percentage concepts.
Strategy to Solve Quadratic Equation Questions
Follow the steps below to solve quadratic equations faster during the exam:
Step-wise Master Strategy
- Understand the Standard Form
Convert equations into the standard form: ax² + bx + c = 0 - Factorize Quickly
Split the middle term to identify two factors whose sum = b and product = ac - Use the Sign Trick
- If c is positive, both roots have the same sign
- If c is negative, the roots have opposite signs
- Compare Roots Carefully
After finding the roots, compare them with the other equation as required
(>, <, =, ≤, ≥, or no relation) - Avoid Solving Completely When Not Needed
Sometimes comparison is possible without calculating exact roots—use logic - Practice with a Timer
Try solving each question in 20–25 seconds to improve exam-time efficiency
