यदि परिमेय गुणांकों वाले द्विघात बहुपद का एक शून्यक \(4+\sqrt{11}\) है, तो दूसरा शून्यक कौन सा होगा?

If one zero of a quadratic polynomial with rational coefficients is \(4+\sqrt{11}\), what will be the other zero?

Explanation opens after your attempt
Correct Answer

A. \(4-\sqrt{11}\)

Step 1

Concept

With rational coefficients \(a+\sqrt{b}\) is accompanied by \(a-\sqrt{b}\). In exams identify conjugate zeroes quickly.

Step 2

Why this answer is correct

The correct answer is A. \(4-\sqrt{11}\). With rational coefficients \(a+\sqrt{b}\) is accompanied by \(a-\sqrt{b}\). In exams identify conjugate zeroes quickly.

Step 3

Exam Tip

परिमेय गुणांकों में \(a+\sqrt{b}\) के साथ \(a-\sqrt{b}\) भी शून्यक होता है। परीक्षा में संयुग्मी शून्यक तुरंत पहचानें।
