Question Hard Mathematics Polynomials Irrational numbers and real numbers Class 10 Level 26

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. \(x^4-10x^2+1=0\)

Step 1

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.

Step 2

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.

Step 3

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।

यदि (p(x)=2x-2-3x+\sqrt{2}), तो यह किस प्रकार का बहुपद है?

If (p(x)=2x-2-3x+\sqrt{2}), what type of polynomial is it?

Explanation opens after your attempt
Correct Answer

A. वास्तविक गुणांकों वाला द्विघात बहुपदQuadratic polynomial with real coefficients

Step 1

Concept

\(\sqrt{2}\) is real but irrational, so the coefficients are real but not all rational. Since the degree is (2), it is quadratic.

Step 2

Why this answer is correct

The correct answer is A. वास्तविक गुणांकों वाला द्विघात बहुपद / Quadratic polynomial with real coefficients. \(\sqrt{2}\) is real but irrational, so the coefficients are real but not all rational. Since the degree is (2), it is quadratic.

Step 3

Exam Tip

\(\sqrt{2}\) वास्तविक लेकिन अपरिमेय है, इसलिए गुणांक वास्तविक हैं पर सभी परिमेय नहीं। घात (2) होने से यह द्विघात है।
