किस द्विघात बहुपद के शून्यक \(2+\sqrt{10}\) और \(2-\sqrt{10}\) हैं?
Which quadratic polynomial has zeroes \(2+\sqrt{10}\) and \(2-\sqrt{10}\)?
Explanation opens after your attempt
A. \(x^2-4x-6\)
Concept
The sum is (4) and the product is (4-10=-6). Hence the polynomial is \(x^2-4x-6\).
Why this answer is correct
The correct answer is A. \(x^2-4x-6\). The sum is (4) and the product is (4-10=-6). Hence the polynomial is \(x^2-4x-6\).
Exam Tip
योग (4) और गुणनफल (4-10=-6) है। इसलिए बहुपद \(x^2-4x-6\) होगा।
