कौन सा युग्म परिमेय गुणांकों वाले किसी द्विघात बहुपद के अपरिमेय शून्यकों का संभव युग्म है?
Which pair can be irrational zeroes of a quadratic polynomial with rational coefficients?
Explanation opens after your attempt
Correct Answer
A. \(4+\sqrt{6}\) और \(4-\sqrt{6}\)\(4+\sqrt{6}\) and \(4-\sqrt{6}\)
Concept
For rational coefficients, the conjugate \(a-\sqrt{b}\) accompanies \(a+\sqrt{b}\). Hence the first pair is correct.
Why this answer is correct
The correct answer is A. \(4+\sqrt{6}\) और \(4-\sqrt{6}\) / \(4+\sqrt{6}\) and \(4-\sqrt{6}\). For rational coefficients, the conjugate \(a-\sqrt{b}\) accompanies \(a+\sqrt{b}\). Hence the first pair is correct.
Exam Tip
परिमेय गुणांकों के लिए \(a+\sqrt{b}\) का संयुग्मी \(a-\sqrt{b}\) साथ आता है। इसलिए पहला युग्म सही है।
