कौन सा व्यंजक बहुपद नहीं है क्योंकि चर की घात भिन्न है?

Which expression is not a polynomial because the variable has a fractional power?

Explanation opens after your attempt
Correct Answer

C. \(x^{\frac{3}{2}}+x+1\)

Step 1

Concept

In \(x^{\frac{3}{2}}\), the power of the variable is fractional, so it is not a polynomial. In a polynomial, powers are non-negative integers.

Step 2

Why this answer is correct

The correct answer is C. \(x^{\frac{3}{2}}+x+1\). In \(x^{\frac{3}{2}}\), the power of the variable is fractional, so it is not a polynomial. In a polynomial, powers are non-negative integers.

Step 3

Exam Tip

\(x^{\frac{3}{2}}\) में चर की घात भिन्न है, इसलिए यह बहुपद नहीं है। बहुपद में घातें अऋणात्मक पूर्णांक होती हैं।

कौन सा बहुपद (x=0) को शून्य बनाता है लेकिन शून्य बहुपद नहीं है?

Which polynomial makes (x=0) a zero but is not the zero polynomial?

Explanation opens after your attempt
Correct Answer

B. \(4x^3-7x\)

Step 1

Concept

Substituting (x=0) in \(4x^3-7x\) gives (0), and it is not the zero polynomial. For (x=0), the constant term must be (0).

Step 2

Why this answer is correct

The correct answer is B. \(4x^3-7x\). Substituting (x=0) in \(4x^3-7x\) gives (0), and it is not the zero polynomial. For (x=0), the constant term must be (0).

Step 3

Exam Tip

\(4x^3-7x\) में (x=0) रखने पर (0) मिलता है और यह शून्य बहुपद नहीं है। (x=0) के लिए अचर पद (0) होना चाहिए।

कौन सा बहुपद (x=0) को शून्य बनाता है?

Which polynomial makes (x=0) a zero?

Explanation opens after your attempt
Correct Answer

B. \(3x^3-2x\)

Step 1

Concept

Substituting (x=0) in \(3x^3-2x\) gives (0). To make (x=0) a zero, the constant term must be (0).

Step 2

Why this answer is correct

The correct answer is B. \(3x^3-2x\). Substituting (x=0) in \(3x^3-2x\) gives (0). To make (x=0) a zero, the constant term must be (0).

यदि (x=0), (p(x)=7x-3-2x) का शून्यक है, तो कारण क्या है?

If (x=0) is a zero of (p(x)=7x-3-2x), what is the reason?

Explanation opens after your attempt
Correct Answer

A. हर पद में (x) गुणनखंड हैEvery term has factor (x)

Step 1

Concept

(p(x)=x\(7x^2-2\)), so at (x=0) the value is (0). If every term has (x), then (0) is a zero.

Step 2

Why this answer is correct

The correct answer is A. हर पद में (x) गुणनखंड है / Every term has factor (x). (p(x)=x\(7x^2-2\)), so at (x=0) the value is (0). If every term has (x), then (0) is a zero.

Step 3

Exam Tip

(p(x)=x\(7x^2-2\)), इसलिए (x=0) पर मान (0) होता है। यदि हर पद में (x) हो, तो (0) शून्यक होता है।
