यदि (p(5)\neq 0), तो (5) के बारे में क्या कहा जाएगा?

If (p(5)\neq 0), what can be said about (5)?

Explanation opens after your attempt
Correct Answer

A. (5) शून्यक नहीं है(5) is not a zero

Step 1

Concept

For (5) to be a zero, (p(5)=0) is necessary. If (p(5)\neq 0), then (5) is not a zero.

Step 2

Why this answer is correct

The correct answer is A. (5) शून्यक नहीं है / (5) is not a zero. For (5) to be a zero, (p(5)=0) is necessary. If (p(5)\neq 0), then (5) is not a zero.

Step 3

Exam Tip

शून्यक होने के लिए (p(5)=0) जरूरी है। यदि (p(5)\neq 0), तो (5) शून्यक नहीं है।

यदि (p(x)=2x+6), तो ग्राफ का (x)-अक्ष से कटाव किस (x)-मान पर होगा?

If (p(x)=2x+6), at which (x)-value will the graph cut the (x)-axis?

Explanation opens after your attempt
Correct Answer

A. (-3)

Step 1

Concept

On the (x)-axis, (p(x)=0), so (2x+6=0) gives (x=-3). This is the graphical zero.

Step 2

Why this answer is correct

The correct answer is A. (-3). On the (x)-axis, (p(x)=0), so (2x+6=0) gives (x=-3). This is the graphical zero.

Step 3

Exam Tip

(x)-अक्ष पर (p(x)=0), इसलिए (2x+6=0) से (x=-3)। यही ग्राफीय शून्यक है।

यदि (p(0)=4), तो क्या (0) बहुपद का शून्यक है?

If (p(0)=4), is (0) a zero of the polynomial?

Explanation opens after your attempt
Correct Answer

A. नहींNo

Step 1

Concept

For (0) to be a zero, (p(0)=0) must be true. Here (p(0)=4), so (0) is not a zero.

Step 2

Why this answer is correct

The correct answer is A. नहीं / No. For (0) to be a zero, (p(0)=0) must be true. Here (p(0)=4), so (0) is not a zero.

Step 3

Exam Tip

शून्यक होने के लिए (p(0)=0) होना चाहिए। यहाँ (p(0)=4), इसलिए (0) शून्यक नहीं है।

किसी बहुपद के ग्राफ पर शून्यक पहचानने के लिए कौन-सा मान शून्य होना चाहिए?

Which value must be zero to identify a zero on the graph of a polynomial?

Explanation opens after your attempt
Correct Answer

A. बहुपद का मानValue of the polynomial

Step 1

Concept

At a zero, the polynomial value is (0). While reading a graph, look for points where (y=0).

Step 2

Why this answer is correct

The correct answer is A. बहुपद का मान / Value of the polynomial. At a zero, the polynomial value is (0). While reading a graph, look for points where (y=0).

Step 3

Exam Tip

शून्यक पर बहुपद का मान (0) होता है। ग्राफ पढ़ते समय (y=0) वाले बिंदु देखें।

यदि (p(2)=5), तो क्या (2) बहुपद का शून्यक है?

If (p(2)=5), is (2) a zero of the polynomial?

Explanation opens after your attempt
Correct Answer

A. नहींNo

Step 1

Concept

For (2) to be a zero, (p(2)=0) must hold. Here (p(2)=5), so (2) is not a zero.

Step 2

Why this answer is correct

The correct answer is A. नहीं / No. For (2) to be a zero, (p(2)=0) must hold. Here (p(2)=5), so (2) is not a zero.

Step 3

Exam Tip

शून्यक होने के लिए (p(2)=0) होना चाहिए। यहाँ (p(2)=5), इसलिए (2) शून्यक नहीं है।

किस स्थिति में (x=2) बहुपद (p(x)) का शून्यक कहलाएगा?

In which situation will (x=2) be called a zero of polynomial (p(x))?

Explanation opens after your attempt
Correct Answer

A. जब (p(2)=0) होWhen (p(2)=0)

Step 1

Concept

A value is called a zero only when the polynomial value at that point is (0). So for (x=2), (p(2)=0) is required.

Step 2

Why this answer is correct

The correct answer is A. जब (p(2)=0) हो / When (p(2)=0). A value is called a zero only when the polynomial value at that point is (0). So for (x=2), (p(2)=0) is required.

Step 3

Exam Tip

किसी मान को शून्यक तभी कहते हैं जब उस पर बहुपद का मान (0) हो। इसलिए (x=2) के लिए (p(2)=0) होना चाहिए।
