What is a Quadratic Equation?

A quadratic equation is a polynomial equation of degree two, generally represented as:
ax² + bx + c = 0, where a ≠ 0

The solutions (roots) of the equation can be found using factorization or the quadratic formula. In RBI Assistant exams, the focus is mainly on comparing roots of two equations rather than solving lengthy problems.

Types of Quadratic Equation Questions Asked

In the RBI Assistant Exam, questions are mostly based on comparing two quadratic equations. You are given two equations (I and II), and you need to determine the relationship between their roots.

Common Answer Patterns

1. x > y
2. x < y
3. x ≥ y
4. x ≤ y
5. x = y or no relation

Example Question

Equation I: x² – 5x + 6 = 0
Equation II: y² – 7y + 10 = 0

Step 1: Solve Equation I

x² – 5x + 6 = 0
(x – 2)(x – 3) = 0
x = 2, 3

Step 2: Solve Equation II

y² – 7y + 10 = 0
(y – 5)(y – 2) = 0
y = 2, 5

Step 3: Compare Roots

x = 2, 3 and y = 2, 5
Here, we cannot establish a definite relationship between x and y

Correct Answer: No relation

Important Concepts to Remember

1. Nature of Roots

The discriminant formula helps determine the nature of roots:
D = b² – 4ac

• If D > 0 → Real and distinct roots
• If D = 0 → Real and equal roots
• If D < 0 → Imaginary roots

2. Sum and Product of Roots

• Sum of roots = –b/a
• Product of roots = c/a

These formulas can help in quicker comparisons without full factorization.

Short Tricks to Solve Faster

1. Factorization First

Try splitting the middle term for quick solutions. Most exam questions are designed to be factorized easily.

2. Avoid Lengthy Calculations

Do not use the quadratic formula unless necessary. Factorization saves time.

3. Compare Ranges

Instead of comparing each root individually, try identifying the range in which roots lie.

4. Practice Approximation

Sometimes, approximation helps in quickly determining the relationship between roots.

Preparation Strategy for RBI Assistant

1. Understand the Basics

Start with understanding factorization and the concept of roots. Without clarity, speed cannot be achieved.

2. Practice Daily

Solve at least 15–20 quadratic equation questions every day. Regular practice improves accuracy and speed.

3. Focus on Accuracy

Since these questions are easy, accuracy should be 100%. Avoid careless mistakes.

4. Take Mock Tests

Practice with sectional and full-length mock tests to improve time management.

5. Analyze Mistakes

Always review incorrect attempts to understand where you went wrong.

Common Mistakes to Avoid

• Ignoring negative signs while solving equations
• Making errors in factorization
• Comparing roots incorrectly
• Spending too much time on a single question

Final Tips

• Attempt these questions early in the exam
• Stick to basic methods for faster solving
• Revise formulas regularly
• Practice consistently to improve speed

Conclusion

Quadratic Equation questions in the RBI Assistant Exam are simple, scoring, and highly predictable. With a clear understanding of concepts and consistent practice, you can easily master this topic. Make use of free PDFs, attempt mock tests, and focus on accuracy to maximize your score. A strong command over quadratic equations can give you a significant edge in the Quantitative Aptitude section.
