What is a Quadratic Equation?
A quadratic equation is a polynomial equation of degree two and is generally written in the following standard form:
ax² + bx + c = 0
Where:
- a, b, and c are constants
- x is the variable
- a ≠ 0
The main objective in quadratic equations is to find the values of x that satisfy the equation.
Types of Quadratic Equation Questions in Banking Exams
In banking exams like IDBI JAM, quadratic equation questions are usually asked in comparison format. Candidates are given two equations and must find the relationship between x and y.
The possible relationships include:
- x > y
- x < y
- x ≥ y
- x ≤ y
- x = y
- Relationship cannot be determined
These questions test both conceptual understanding and calculation speed.
Example of a Quadratic Equation Question
Let’s look at a typical example:
Equation I:
x² – 7x + 12 = 0
Equation II:
y² – 9y + 20 = 0
Step 1: Solve Equation I
x² – 7x + 12 = 0
(x – 3)(x – 4) = 0
So, x = 3 or x = 4
Step 2: Solve Equation II
y² – 9y + 20 = 0
(y – 4)(y – 5) = 0
So, y = 4 or y = 5
Step 3: Compare the Values
Possible values of x = 3, 4
Possible values of y = 4, 5
Since the relationship varies depending on the values, the relationship cannot be determined.
This type of question is very common in banking exams and can be solved quickly with practice.
Methods to Solve Quadratic Equations
There are several methods to solve quadratic equations, but the following two methods are most useful for competitive exams.
1. Factorization Method
This is the fastest and most commonly used method.
Steps:
- Convert the equation into standard form.
- Factorize the equation.
- Find the values of the variable.
Example:
x² – 5x + 6 = 0
(x – 2)(x – 3) = 0
x = 2, 3
2. Quadratic Formula
If the equation cannot be factorized easily, the quadratic formula can be used.
Formula:
x = (-b ± √(b² – 4ac)) / 2a
Where:
a, b, and c are constants from the equation ax² + bx + c = 0.
Although this method is slightly longer, it helps solve complex equations.
Tips to Solve Quadratic Equation Questions Quickly
Here are some effective tips for solving quadratic equation questions in the IDBI JAM exam.
1. Practice Factorisation
Most quadratic equations in banking exams are designed to be solved quickly using factorisation. Practising this method regularly can improve your speed.
2. Improve Calculation Speed
Strong calculation skills help solve equations faster. Practice mental math and multiplication tables.
3. Learn Common Patterns
Many equations follow common patterns that can be recognised easily with practice.
4. Attempt Mock Tests
Mock tests help you understand the exam pattern and improve time management.
5. Practice Previous Year Questions
Solving previous exam questions helps you understand the level of difficulty and question types.
Conclusion
Quadratic equations are one of the easiest and most scoring topics in the Quantitative Aptitude section of the IDBI JAM Grade O exam. With a clear understanding of concepts and consistent practice, candidates can solve these questions quickly and accurately. If you are preparing for the IDBI JAM Grade O 2026 exam, make sure to include quadratic equation questions in your daily practice routine.
