किस बहुपद के शून्यक \(1+\sqrt{2}\) और \(1-\sqrt{2}\) हैं?
Which polynomial has zeroes \(1+\sqrt{2}\) and \(1-\sqrt{2}\)?
Explanation opens after your attempt
A. \(x^2-2x-1\)
Concept
The sum is (2) and the product is (-1). So the polynomial is \(x^2-2x-1\).
Why this answer is correct
The correct answer is A. \(x^2-2x-1\). The sum is (2) and the product is (-1). So the polynomial is \(x^2-2x-1\).
Exam Tip
योग (2) और गुणनफल (-1) है। इसलिए बहुपद \(x^2-2x-1\) है।
