किस बहुपद के शून्यक \(\sqrt{2}+\sqrt{3}\) और \(\sqrt{2}-\sqrt{3}\) हैं?
Which polynomial has zeroes \(\sqrt{2}+\sqrt{3}\) and \(\sqrt{2}-\sqrt{3}\)?
Explanation opens after your attempt
Correct Answer
A. \(x^2-2\sqrt{2}x-1\)
Concept
The sum is \(2\sqrt{2}\) and the product is (2-3=-1). Hence the polynomial is \(x^2-2\sqrt{2}x-1\).
Why this answer is correct
The correct answer is A. \(x^2-2\sqrt{2}x-1\). The sum is \(2\sqrt{2}\) and the product is (2-3=-1). Hence the polynomial is \(x^2-2\sqrt{2}x-1\).
Exam Tip
योग \(2\sqrt{2}\) और गुणनफल (2-3=-1) है। इसलिए बहुपद \(x^2-2\sqrt{2}x-1\) बनेगा।
