Quadratic equation forms the basic part of algebra in JEE mathematics. A bit onthis topic is already learnt by many students in their previous classes. A quadratic equation is relatively easy to understand. Like Trigonometry, direct questions from quadratic equation are rarely asked in JEE Advance. Question from quadratic equation will always be clubbed with any other part of the JEE math syllabus. But for JEE Main, which is relatively simple there will be direct questions from the topic. Graphical representation of the given quadratic equation is very useful. Always try to solve questions by graphical methods as they consume less time and efforts. Within a limited time, you can solve the question quickly. As you know that equation of the parabola is quadratic, and its proficiency in quadratic equation will definitely help you for topic co-ordinate geometry. Here are some points that you must keep in your mind while solving questions of quadratic equation to avoid getting wrong answers:

Pay attention to signs of roots (positive and negative) to avoid getting negative marks after solving complete questions.
After getting the solution of an equation, fill in back the solution in equation to check whether it’s actually a solution or not. There are some cases when the solution you get doesn’t satisfy the equation and you end up getting negative marks.
Many conditions and standard result which is there in quadratic equation are quite confusing and therefore try to remember conditions using their graphical representation so that it will be retained in your memory for a long time. Quadratic equation plays important role in physics questions as well as in some part of chemistry, so don’t neglect it. Also Quadratic equation is well related to complex numbers, as the origin of complex numbers is because of no real solution condition of quadratic equations.
