Top 5 Videos on Quadratic Equations for CAT Quantitative Aptitude by PW

Quadratic Equation questions in CAT Quantitative Aptitude can involve much more than solving an equation. You may need to interpret the roots, use relationships between coefficients and roots, analyse a parabola or find the maximum or minimum value of an expression. Choosing the right method becomes especially important when you are solving questions under time pressure.

Physics Wallah’s videos cover these concepts through explanations, solved examples, shortcuts and CAT previous-year questions (PYQs). You can strengthen your basics, understand how algebraic and graphical methods connect, and practise different question patterns.

The following five videos offer options for learning the topic from scratch, revising individual concepts or reviewing Quadratic Equations alongside the wider Algebra syllabus.

Video 1. Connect Roots, Graphs and Extreme Values Through Solved Questions

This lesson of PW’s MBA Wallah begins with an introduction and recap of Quadratic Equations before explaining roots and their interpretation. Solved CAT questions demonstrate how root-based problems can be approached.

The session then introduces graphical representations through parabolas and their vertices, followed by maximum and minimum values of quadratic expressions. This combination helps you understand the topic through both algebraic calculations and visual representations.

Use this video if you know the basic equation-solving methods but need help with root-based applications, graphs or extreme values. Pay attention to how each question is approached and when a graphical interpretation can help. Practising these connections can improve your understanding of different Quadratic Equation question types.

Video 2. Revise Quadratic Equations with a One-Shot Lesson and CAT PYQs

This one-shot lesson revises the main concepts of Quadratic Equations for CAT and other MBA entrance examinations. It includes practice questions, alternative solving methods, shortcuts and recent CAT PYQs from the topic. By working through different problems, you can revise the concepts and understand how to approach questions that require different methods.

Choose this lesson if you have already studied the chapter and want to revise it before a mock test or sectional practice.

Attempt each question before watching its solution, then compare your method with the one explained. This will help you identify where you can simplify calculations and select a more efficient approach.

Video 3. Revise Graphs, Identities and PYQs in One Complete Lesson

This lesson covers the standard form of a quadratic equation, solving methods, types of roots, relationships between coefficients and roots, identities and common-root problems. It also includes integer conditions, minimum values, quadratic graphs, vertices and symmetry. CAT PYQs, shortcuts, mental calculation techniques and a final challenge bring several concepts together through practice.

Use this video when you want to revise multiple parts of the chapter without studying each concept separately. Focus on recognising which method suits each question, whether it involves algebraic manipulation, root properties or a graph. Solving the practice questions independently will help you identify concepts that need further revision before timed CAT practice.

Video 4. Strengthen Root Properties with Step-by-Step Algebra Practice

This lecture introduces the standard form of a quadratic equation and explains roots as values that satisfy the equation. It revises splitting the middle term and the quadratic formula before covering relationships between coefficients and roots.

Further topics include forming equations from known roots, common-root questions, shared-root applications, warm-up problems and practice polls. The lesson also highlights common errors to watch for while solving algebraic questions.

If you find property-based questions difficult, start by revisiting the basic solving methods before moving to relationships between roots and coefficients. Practise translating the conditions in each question into equations instead of relying on memorised patterns.

This can help you handle common-root problems more accurately during CAT preparation.

Video 5. Strengthen Quadratic Equations During Full Algebra Revision

This Algebra one-shot places Quadratic Equations alongside linear equations, inequalities, logarithms, functions, graphs and optimisation. Its Quadratic Equation coverage includes factorisation, rational and irrational roots, discriminant-based cases, conjugate roots, root manipulation, identities and common-root problems. Parabolas, vertices, extreme values, CAT-level questions and solving strategies are also covered.

Choose this lesson when you want to revise Quadratic Equations as part of the wider Algebra syllabus. Switching between related topics can help you practise recognising which concept a question requires. Use the quadratic portion to revisit weak areas, then attempt mixed Algebra questions to check whether you can apply the methods without relying on topic-specific prompts.

These five PW videos cover Quadratic Equations for CAT Quantitative Aptitude through root properties, graphs, identities, maximum and minimum values, and previous-year questions. Start with the lesson that matches your current preparation level, practise the methods independently and use one-shot sessions for revision.

Regular practice can help you recognise question patterns, reduce calculation errors and solve Quadratic Equation problems more efficiently during CAT mocks.
