What are Quadratic Equations for SBI PO 2026?
Quadratic Equations are algebraic equations of degree two and are one of the easiest topics in the SBI PO Quantitative Aptitude syllabus. Unlike lengthy arithmetic questions, Quadratic Equations for SBI PO 2026 can be solved quickly if you follow the correct solving method and practise regularly.
In the SBI PO exam, you are usually given two quadratic equations—one containing x and the other containing y. After solving both equations, you have to compare their roots and choose the correct relationship between x and y.
The possible answers are generally:
- x > y
- x < y
- x ≥ y
- x ≤ y
- x = y or Relationship Cannot Be Determined (CND)
Types of Quadratic Equation questions asked in SBI PO PDF
There are certain types of questions that are asked in the exam. To have an idea about the types of questions asked, we have curated a PDF that is according to the SBI PO exam pattern. The link to the SBI PO Quadratic Equation questions pdf is given below.
SBI PO Quadratic Equations Weightage and Previous Year Trends
One of the biggest reasons to prepare Quadratic Equations is their consistent appearance in the exam over the years. Direct quadratic equation questions are generally asked in the SBI PO Prelims exam, making this a highly scoring topic. In the Mains exam, the concepts of roots, equations, and algebra also help candidates solve advanced Quantitative Aptitude questions more accurately and efficiently.
Types of Quadratic Equation Questions Asked in SBI PO
The SBI PO exam usually asks comparison-based quadratic equation questions. However, the format can vary slightly every year. Candidates should practise different question types instead of relying on only one pattern. The most common types include:
1. Standard Quadratic Equation Comparison: You are given two equations. Solve both and compare the values of x and y.
Example:
- x² – 9x + 20 = 0
- y² – 11y + 30 = 0
2. Quadratic Equations with Coefficients: Sometimes the coefficient of x² or y² is greater than one. Candidates must remember to divide the roots by the coefficient after factorisation.
Example:
- 2x² – 14x + 24 = 0
3. Missing Middle Term Questions: These questions look difficult but become easy once you apply the identity method.
Example:
- x² – 49 = 0
4. Questions with Square Roots or Algebraic Values: These are more likely to appear in higher-level banking exams or advanced practice sets. Candidates should understand how to compare irrational roots carefully.
Example:
- If x = √5 and y = 2, then x > y because √5 ≈ 2.24.
Basic Formula Every Candidate Should Know for Quadratic Equations
Instead of directly applying lengthy formulas every time, SBI PO questions are usually solved faster using factorisation and sign analysis. Before learning shortcut tricks for Quadratic Equations for SBI PO 2026, every aspirant should know the standard quadratic equation:
ax² + bx + c = 0
where:
- a ≠ 0
- x is the unknown variable.
Golden Sign Rule for Quadratic Equations
One of the most useful Quadratic Equations for SBI PO 2026 tricks is the Golden Sign Rule. Before calculating the roots, observe the signs in the equation. It gives you an immediate idea about whether the roots will be positive or negative. Learning these simple rule helps eliminate wrong options quickly and reduces calculation time during the exam.
| Equation Pattern | Nature of Roots |
| – – | One Positive, One Negative |
| + + | Both Negative |
| – + | Both Positive |
| + – | One Positive, One Negative |
Important Concepts Before Solving Quadratic Equations
These simple concepts help improve both speed and accuracy in the SBI PO Quant section. Before solving any question, remember these important points:
- Always simplify the equation first.
- Factorise whenever possible instead of using lengthy formulas.
- Divide by the coefficient of x² or y² if required.
- Compare every possible root before selecting the answer.
- If the roots overlap, choose Relationship Cannot Be Determined (CND).
Shortcut Tricks to Solve Quadratic Equations Faster in SBI PO
Learning a few shortcuts can help you solve Quadratic Equations for SBI PO 2026 much faster in the exam. Instead of solving every equation from scratch, first identify the signs of the roots, factorise smartly, and compare the values carefully. These tricks save valuable time in both Prelims and Mains while reducing calculation errors.
1. Check the Sign of the Roots First: Before finding the actual roots, identify whether they are positive or negative. Such simple observation helps you eliminate options quickly.
| Equation Form | Nature of Roots |
| x² − bx + c = 0 | Both roots are positive |
| x² + bx + c = 0 | Both roots are negative |
| x² − bx − c = 0 | One positive, one negative |
| x² + bx − c = 0 | One positive, one negative |
2. Split the Middle Term Smartly: Once you identify these numbers, factorisation becomes easy and you can find the roots within seconds. Find two numbers that:
- Multiply to A × C
- Add up to B
3. Always Divide by the Coefficient: Many candidates forget this step and lose easy marks. If the coefficient of x² is not 1, remember to divide the obtained roots by that coefficient.
Example:
2x² − 10x + 12 = 0
Factorise:
2(x − 2)(x − 3) Roots = 2 and 3
4. Compare Every Possible Root: Never compare only one root. When comparing x and y, check every combination.
- If all x roots are greater than y roots → x > y
- If all x roots are smaller → x < y
- If comparisons overlap → Cannot Be Determined (CND)
