Mathematics - Quadratic Equation

Practise 11 COMEDK previous year questions on Quadratic Equation, compiled from papers spanning 2012 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty COMEDK tests.

Quadratic Equation has been asked in 9 of the 15 years of COMEDK papers analysed (2012–2026), with 11 questions in all. 45% of them were easy, 27% moderate and 27% tough. Most of its questions came from 2018, with 2 questions that year. In the last three years (2024–2026) it had 2 questions across 2 papers, about 1 per paper.

The chapter's 3 topics are not weighted equally: Relation between Roots and Coefficients (8 questions, 73%), N degree equation (2 questions, 18%), and Graph and Sign of Quadratic (1 question, 9%) have been asked the most. Over the last five years the most frequent topics have been Graph and Sign of Quadratic (1) and Relation between Roots and Coefficients (1). Relation between Roots and Coefficients has produced the most tough questions (3).
