किस बहुपद के शून्यक \(1+\sqrt{10}\) और \(1-\sqrt{10}\) हैं?
Which polynomial has zeroes \(1+\sqrt{10}\) and \(1-\sqrt{10}\)?
Explanation opens after your attempt
Correct Answer
A. \(x^2-2x-9\)
Concept
The sum is (2) and the product is (1-10=-9). So the polynomial is \(x^2-2x-9\).
Why this answer is correct
The correct answer is A. \(x^2-2x-9\). The sum is (2) and the product is (1-10=-9). So the polynomial is \(x^2-2x-9\).
Exam Tip
योग (2) और गुणनफल (1-10=-9) है। इसलिए बहुपद \(x^2-2x-9\) है।
