किस बहुपद के शून्यक \(\sqrt{7}\) और \(-\sqrt{7}\) हैं?
Which polynomial has zeroes \(\sqrt{7}\) and \(-\sqrt{7}\)?
Explanation opens after your attempt
Correct Answer
A. \(x^2-7\)
Concept
The sum of zeroes is (0) and the product is (-7). Hence the polynomial is \(x^2-7\).
Why this answer is correct
The correct answer is A. \(x^2-7\). The sum of zeroes is (0) and the product is (-7). Hence the polynomial is \(x^2-7\).
Exam Tip
शून्यकों का योग (0) और गुणनफल (-7) है। इसलिए बहुपद \(x^2-7\) होगा।
