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
A. \(4-\sqrt{11}\)
Concept
With rational coefficients \(a+\sqrt{b}\) is accompanied by \(a-\sqrt{b}\). In exams identify conjugate zeroes quickly.
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.
Exam Tip
परिमेय गुणांकों में \(a+\sqrt{b}\) के साथ \(a-\sqrt{b}\) भी शून्यक होता है। परीक्षा में संयुग्मी शून्यक तुरंत पहचानें।
