These questions are not only easy to solve with the right approach but also help you save valuable time during the exam. With consistent practice and a clear understanding of concepts, you can turn this topic into your strongest area. In this blog, we’ll cover everything you need to know about quadratic equation questions, including types, preparation strategy, shortcuts, and how to effectively use a free PDF for practice.
Quadratic Equation Questions for IDBI Grade O Exam 2026
In this section, we are providing Quadratic Questions. Our experts curate these after analysing previous years’ patterns. Download Now and practice as many questions as you can.
What is a Quadratic Equation
A quadratic equation is a polynomial equation of degree 2, generally written in the form:
where a ≠ 0, and a, b, c are constants.
The goal is to find the values of x that satisfy the equation. These values are called the roots of the equation.
Why Quadratic Equations are Important for IDBI JAM
- Frequently asked in prelims exams
- Easy to solve with practice
- Less time-consuming compared to arithmetic problems
- High accuracy and scoring potential
If prepared well, you can solve these questions within 20–30 seconds.
Types of Quadratic Equation Questions
Understanding the different question formats is key to mastering this topic.
1. Comparison-Based Questions
Two quadratic equations are given, and you need to compare the roots.
Example Pattern:
Equation I and Equation II are given. Find the relationship between x and y.
2. Roots Finding Questions
You may be asked to find the exact values of roots.
3. Nature of Roots
Questions may test whether the roots are real, equal, or imaginary.
4. Simplification-Based Quadratics
Some questions involve simplifying expressions before solving the equation.
Methods to Solve Quadratic Equations
1. Factorization Method
This is the fastest method when the equation is easily factorable.
Example:
x² – 5x + 6 = 0
(x – 2)(x – 3) = 0
x = 2, 3
2. Quadratic Formula Method
Use this method when factorization is not easy.
3. Splitting the Middle Term
Break the middle term into two parts to factorize easily.
Important Concepts to Remember
- If D = b² – 4ac > 0, roots are real and distinct
- If D = 0, roots are real and equal
- If D < 0, roots are imaginary
Preparation Strategy for Quadratic Equations
A focused approach can help you master this topic quickly.
1. Strengthen Basics
Understand factorization and simplification thoroughly.
2. Practice Comparison Questions
These are commonly asked in exams. Focus on solving both equations quickly.
3. Learn Shortcuts
- Avoid solving completely if comparison can be done early
- Check signs of roots to eliminate options
4. Maintain Speed
Aim to solve each question within 30 seconds.
5. Solve Previous Year Questions
This will help you understand the pattern and difficulty level.
Common Mistakes to Avoid
- Calculation errors in factorization
- Ignoring negative signs
- Spending too much time on one question
- Not checking all possible roots
Tips to Score Maximum Marks
- Always try factorization first
- Use the quadratic formula only when necessary
- Practice daily to build speed
- Focus on accuracy rather than attempts
