What is a Quadratic Equation?

A quadratic equation is a second-degree equation in the form:

genui{“math_block_widget_always_prefetch_v2”:{“content”:”ax^2 + bx + c = 0″}}

Where:

• a, b, c are constants
• a ≠ 0
• x is the variable

Types of Quadratic Equation Questions

1. Solving Quadratic Equations

You may be asked to find the values of x.

Example:
x² – 5x + 6 = 0
Factorizing: (x – 2)(x – 3) = 0
So, x = 2, 3

2. Comparison of Roots

Two quadratic equations are given, and you need to compare their roots.

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

After solving both, compare the roots and choose the correct relation.

3. Nature of Roots

You may be asked to identify whether roots are real, equal, or imaginary.

The nature of roots depends on the discriminant:

D = b^2 – 4ac

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

4. Word-Based Quadratic Problems

These involve forming a quadratic equation from a given situation and solving it.

Important Concepts and Shortcuts

1. Factorization Method

This is the fastest way to solve quadratic equations in exams. Look for two numbers whose sum is b and product is c.

2. Quadratic Formula

When factorization is difficult, use the formula:

genui{“math_block_widget_always_prefetch_v2”:{“content”:”x = \frac{-b \pm \sqrt{b^2 – 4ac}}{2a}”}}

3. Sum and Product of Roots

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

These relations are useful in comparison-based questions.

Tricks to Solve Quadratic Equation Questions Quickly

• Try factorization first before using formulas
• Learn squares and multiplication tables up to 30
• Use approximation in comparison questions
• Avoid lengthy calculations
• Practice mental math for faster solving

Preparation Strategy for RBI Assistant Exam

1. Clear Basic Concepts

Understand the structure of quadratic equations and practice basic problems.

2. Practice Regularly

Solve at least 10–15 questions daily to build speed and accuracy.

3. Focus on Comparison Questions

These are most commonly asked in the exam, so prioritise them.

4. Attempt Mock Tests

Mock tests help in time management and identifying weak areas.

5. Analyze Mistakes

Review incorrect attempts and revise concepts accordingly.
