51 Fully Solved Hard Problems in Quadratic Equations: With Detailed Hints and Full Solutions

By Dr. Samudra Dasgupta

Every problem is JEE Advanced / Olympiad caliber, aimed at Grade XI-XII students ready to go beyond the syllabus. No filler, no easy warm-ups - just the questions that separate a good student from a future mathematician.

Each of the 51 problems is worked through four stages, so you get exactly as much help as you need and no more:
- The Problem - attempt it on paper, with no hints, first.
- First Hint - a small nudge: a way to look at the problem, not the method.
- Second Hint - if the first wasn't enough, the stronger push: the key idea or substitution.
- Full Solution - a complete, worked derivation from setup to final answer.

A closing section of identities, common traps, and speed techniques rounds the book out as a standing reference.

Written by Dr. Samudra Dasgupta - AIR 149, IIT-JEE; B.Tech, IIT Kharagpur; MS, Harvard University; PhD, University of Tennessee - this book wasn't built to help you merely clear an exam. It was built to develop a real love of the subject, for the student who wants to go further.

This eBook edition preserves the exact mathematical typesetting of the print edition and is best read on a tablet, phone, computer, or the free Kindle app - not optimized for basic e-ink Kindle devices. A paperback edition is also available.
