किस विकल्प में दिया बहुपद परिमेय गुणांकों वाला है और उसके शून्यक अपरिमेय संयुग्मी हैं?
Which option gives a polynomial with rational coefficients and irrational conjugate zeroes?
Explanation opens after your attempt
Correct Answer
A. \(x^2-6x+7\)
Concept
For \(x^2-6x+7\), (D=36-28=8). The coefficients are rational and the zeroes are \(3\pm\sqrt{2}\).
Why this answer is correct
The correct answer is A. \(x^2-6x+7\). For \(x^2-6x+7\), (D=36-28=8). The coefficients are rational and the zeroes are \(3\pm\sqrt{2}\).
Exam Tip
\(x^2-6x+7\) में (D=36-28=8) है। गुणांक परिमेय हैं और शून्यक \(3\pm\sqrt{2}\) होंगे।
