QUESTION:
👉 “If the zeroes of the polynomial ax² + bx + (2a/b) are reciprocal of each other, then the value of b is — ”
Options:
A) 2  B) ½  C) –2  D) –½

In this video, we solve a conceptual and exam-style question from Polynomials:

This question beautifully tests your understanding of the relationship between coefficients and zeroes of a quadratic polynomial.

In this session, you’ll learn:
✔️ What it means when the zeroes are reciprocals of each other
✔️ Step-by-step reasoning to find the correct value of b
✔️ The connection between sum and product of zeroes and polynomial coefficients

This video is perfect for CBSE Class 10, IGCSE Year 9/10, or anyone revising the Polynomials chapter.
We’ll break it down conceptually and show how such questions can be solved in less than 60 seconds with the right trick!
