यदि \(\alpha\) और \(\beta\) किसी द्विघात बहुपद के शून्यक हैं, जहां \(\alpha+\beta=8\) और \(\alpha\beta=11\), तो संभावित शून्यक कौन से हैं?
Explanation opens after your attempt
Correct Answer
A. \(4+\sqrt{5}\) और \(4-\sqrt{5}\)\(4+\sqrt{5}\) and \(4-\sqrt{5}\)
Concept
The sum of \(4+\sqrt{5}\) and \(4-\sqrt{5}\) is (8), and the product is (16-5=11). In exams check the sum and product of options.
Why this answer is correct
The correct answer is A. \(4+\sqrt{5}\) और \(4-\sqrt{5}\) / \(4+\sqrt{5}\) and \(4-\sqrt{5}\). The sum of \(4+\sqrt{5}\) and \(4-\sqrt{5}\) is (8), and the product is (16-5=11). In exams check the sum and product of options.
Exam Tip
\(4+\sqrt{5}\) और \(4-\sqrt{5}\) का योग (8) और गुणनफल (16-5=11) है। परीक्षा में विकल्पों का योग और गुणनफल जांचें।
