Question 1/6 Expert Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 24

किसी द्विघात बहुपद का ग्राफ (x)-अक्ष को नहीं छूता। उसके विविक्त वास्तविक शून्यकों की संख्या क्या होगी?

A quadratic polynomial graph does not touch the (x)-axis. What is the number of distinct real zeroes?

Explanation opens after your attempt
Correct Answer

A. शून्यZero

Step 1

Concept

For a real zero the graph must meet the (x)-axis. No meeting means no real zero.

Step 2

Why this answer is correct

The correct answer is A. शून्य / Zero. For a real zero the graph must meet the (x)-axis. No meeting means no real zero.

Step 3

Exam Tip

वास्तविक शून्यक के लिए ग्राफ का (x)-अक्ष से मिलना जरूरी है। कोई मिलन नहीं तो कोई वास्तविक शून्यक नहीं।

Question 2/6 Expert Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 23

यदि (p(x)=5x-2+20x+23) है, तो ग्राफ (x)-अक्ष के सापेक्ष कैसा होगा?

If (p(x)=5x-2+20x+23), how will the graph be with respect to the (x)-axis?

Explanation opens after your attempt
Correct Answer

C. नहीं काटेगाIt will not cut

Step 1

Concept

The discriminant is (400-460=-60), so there are no real zeroes. Tip: with negative discriminant a parabola does not meet the (x)-axis.

Step 2

Why this answer is correct

The correct answer is C. नहीं काटेगा / It will not cut. The discriminant is (400-460=-60), so there are no real zeroes. Tip: with negative discriminant a parabola does not meet the (x)-axis.

Step 3

Exam Tip

विविक्तकर (400-460=-60) है, इसलिए वास्तविक शून्यक नहीं हैं। टिप: ऋणात्मक विविक्तकर पर परवलय (x)-अक्ष से नहीं मिलता।

Question 3/6 Expert Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 22

यदि (p(x)=4x-2+16x+21) है, तो ग्राफ (x)-अक्ष के सापेक्ष कैसा होगा?

If (p(x)=4x-2+16x+21), how will the graph be with respect to the (x)-axis?

Explanation opens after your attempt
Correct Answer

C. नहीं काटेगाIt will not cut

Step 1

Concept

The discriminant is (256-336=-80), so there are no real zeroes. Tip: with negative discriminant a parabola does not meet the (x)-axis.

Step 2

Why this answer is correct

The correct answer is C. नहीं काटेगा / It will not cut. The discriminant is (256-336=-80), so there are no real zeroes. Tip: with negative discriminant a parabola does not meet the (x)-axis.

Step 3

Exam Tip

विविक्तकर (256-336=-80) है, इसलिए वास्तविक शून्यक नहीं हैं। टिप: ऋणात्मक विविक्तकर पर परवलय (x)-अक्ष से नहीं मिलता।

Question 4/6 Hard Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 24

यदि (p(x)=3x-2+12x+17) है तो ग्राफ (x)-अक्ष के सापेक्ष कैसा होगा?

If (p(x)=3x-2+12x+17), how will the graph be with respect to the (x)-axis?

Explanation opens after your attempt
Correct Answer

C. नहीं काटेगाIt will not cut

Step 1

Concept

The discriminant is (144-204=-60), so there are no real zeroes. Tip: with negative discriminant a parabola does not meet the (x)-axis.

Step 2

Why this answer is correct

The correct answer is C. नहीं काटेगा / It will not cut. The discriminant is (144-204=-60), so there are no real zeroes. Tip: with negative discriminant a parabola does not meet the (x)-axis.

Step 3

Exam Tip

विविक्तकर (144-204=-60) है इसलिए वास्तविक शून्यक नहीं हैं। टिप: ऋणात्मक विविक्तकर पर परवलय (x)-अक्ष से नहीं मिलता।

Question 5/6 Hard Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 23

यदि (p(x)=2x-2+8x+11) है, तो ग्राफ (x)-अक्ष के सापेक्ष कैसा होगा?

If (p(x)=2x-2+8x+11), how will the graph be with respect to the (x)-axis?

Explanation opens after your attempt
Correct Answer

C. नहीं काटेगाIt will not cut

Step 1

Concept

The discriminant is (64-88=-24), so there are no real zeroes. Tip: with negative discriminant a parabola does not meet the (x)-axis.

Step 2

Why this answer is correct

The correct answer is C. नहीं काटेगा / It will not cut. The discriminant is (64-88=-24), so there are no real zeroes. Tip: with negative discriminant a parabola does not meet the (x)-axis.

Step 3

Exam Tip

विविक्तकर (64-88=-24) है, इसलिए वास्तविक शून्यक नहीं हैं। टिप: ऋणात्मक विविक्तकर पर परवलय (x)-अक्ष से नहीं मिलता।

Question 6/6 Easy Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 22

यदि किसी बहुपद का ग्राफ (x)-अक्ष को नहीं काटता और नहीं छूता, तो उसके वास्तविक शून्यकों की संख्या क्या होगी?

If the graph of a polynomial neither cuts nor touches the (x)-axis, how many real zeroes does it have?

Explanation opens after your attempt
Correct Answer

A. (0)

Step 1

Concept

Real zeroes appear only where the graph meets the (x)-axis. If it does not meet the (x)-axis, it has no real zero.

Step 2

Why this answer is correct

The correct answer is A. (0). Real zeroes appear only where the graph meets the (x)-axis. If it does not meet the (x)-axis, it has no real zero.

Step 3

Exam Tip

वास्तविक शून्यक तभी दिखते हैं जब ग्राफ (x)-अक्ष से मिले। यदि ग्राफ (x)-अक्ष से नहीं मिलता, तो वास्तविक शून्यक नहीं होंगे।
