The correct answer is A. (-3). (p(-3)=9-3k-18=0), so (-3k=9) and (k=-3). When a zero is given, set the polynomial value equal to (0).

Step 3

Exam Tip

(p(-3)=9-3k-18=0), इसलिए (-3k=9) और (k=-3)। शून्य दिए होने पर बहुपद का मान (0) रखें।

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।

यदि (p(x)=4x-12), तो इसका शून्यक क्या है?

If (p(x)=4x-12), what is its zero?

Explanation opens after your attempt
Correct Answer

A. (3)

Step 1

Concept

From (4x-12=0), we get (x=3). A zero is the value where the polynomial becomes (0).

Step 2

Why this answer is correct

The correct answer is A. (3). From (4x-12=0), we get (x=3). A zero is the value where the polynomial becomes (0).

Step 3

Exam Tip

(4x-12=0) से (x=3) मिलता है। शून्यक वह मान है जहाँ बहुपद का मान (0) हो।

यदि (p(x)=ax+b) और \(a\neq0\), तो इसका शून्यक क्या है?

If (p(x)=ax+b) and \(a\neq0\), what is its zero?

Explanation opens after your attempt
Correct Answer

A. -\(\frac{b}{a}\)

Step 1

Concept

Putting (ax+b=0) gives \(x=-\frac{b}{a}\). A linear polynomial has exactly one zero.

Step 2

Why this answer is correct

The correct answer is A. -\(\frac{b}{a}\). Putting (ax+b=0) gives \(x=-\frac{b}{a}\). A linear polynomial has exactly one zero.

Step 3

Exam Tip

(ax+b=0) रखने पर \(x=-\frac{b}{a}\) मिलता है। रेखीय बहुपद में केवल एक शून्यक होता है।
