यदि \(x=\sqrt{3}+\sqrt{2}\), तो (x) किस द्विघात समीकरण को संतुष्ट करता है?
If \(x=\sqrt{3}+\sqrt{2}\), which quadratic equation does (x) satisfy?
Explanation opens after your attempt
Correct Answer
C. \(x^4-10x^2+1=0\)
Concept
Here \(x^2=5+2\sqrt{6}\) and then (\(x^2-5\)2=24), so \(x^4-10x^2+1=0\). In exams a sum of two radicals may lead to a fourth-degree relation.
Why this answer is correct
The correct answer is C. \(x^4-10x^2+1=0\). Here \(x^2=5+2\sqrt{6}\) and then (\(x^2-5\)2=24), so \(x^4-10x^2+1=0\). In exams a sum of two radicals may lead to a fourth-degree relation.
Exam Tip
\(x^2=5+2\sqrt{6}\) और फिर (\(x^2-5\)2=24), इसलिए \(x^4-10x^2+1=0\) है। परीक्षा में दो वर्गमूलों के योग से कभी द्विघात नहीं बल्कि चतुर्थ घात संबंध भी बन सकता है।
