Hard Mathematics Polynomials Class 10 Level 26

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।
