Question 1/9 Expert Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 24

यदि किसी द्विघात बहुपद के ग्राफ का शीर्ष (x)-अक्ष पर है तो वास्तविक शून्यकों के बारे में क्या सही है?

If the vertex of a quadratic polynomial graph lies on the (x)-axis, what is correct about its real zeroes?

Explanation opens after your attempt
Correct Answer

A. दोनों वास्तविक शून्यक समान हैंBoth real zeroes are equal

Step 1

Concept

When the vertex lies on the (x)-axis, the parabola touches the axis at one point. Hence the zeroes are equal.

Step 2

Why this answer is correct

The correct answer is A. दोनों वास्तविक शून्यक समान हैं / Both real zeroes are equal. When the vertex lies on the (x)-axis, the parabola touches the axis at one point. Hence the zeroes are equal.

Step 3

Exam Tip

शीर्ष (x)-अक्ष पर होने पर परवलय अक्ष को एक ही बिंदु पर छूता है। इसलिए शून्यक समान होते हैं।

Question 5/9 Hard Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 23

यदि किसी परवलय का शीर्ष ((4,0)) है, तो वास्तविक शून्यकों की अलग संख्या क्या होगी?

If the vertex of a parabola is ((4,0)), what will be the distinct number of real zeroes?

Explanation opens after your attempt
Correct Answer

B. एकOne

Step 1

Concept

The vertex lies on the (x)-axis, so the parabola touches at ((4,0)). Tip: if the vertex has (y=0), there is one distinct zero.

Step 2

Why this answer is correct

The correct answer is B. एक / One. The vertex lies on the (x)-axis, so the parabola touches at ((4,0)). Tip: if the vertex has (y=0), there is one distinct zero.

Step 3

Exam Tip

शीर्ष (x)-अक्ष पर है, इसलिए परवलय ((4,0)) पर स्पर्श करेगा। टिप: शीर्ष का (y)-मान (0) हो तो एक अलग शून्यक होता है।

Question 6/9 Hard Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 22

यदि किसी द्विघात ग्राफ का शीर्ष ((-1,0)) है और वह नीचे की ओर खुलता है, तो ग्राफ (x)-अक्ष से कैसे मिलेगा?

If a quadratic graph has vertex ((-1,0)) and opens downward, how will it meet the (x)-axis?

Explanation opens after your attempt
Correct Answer

C. (x=-1) पर स्पर्श करेगाIt will touch at (x=-1)

Step 1

Concept

The vertex lies on the (x)-axis, so the graph touches there. Tip: the opening direction does not change the touching point.

Step 2

Why this answer is correct

The correct answer is C. (x=-1) पर स्पर्श करेगा / It will touch at (x=-1). The vertex lies on the (x)-axis, so the graph touches there. Tip: the opening direction does not change the touching point.

Step 3

Exam Tip

शीर्ष (x)-अक्ष पर है, इसलिए ग्राफ वहीं स्पर्श करता है। टिप: खुलने की दिशा स्पर्श बिंदु नहीं बदलती।

Question 7/9 Hard Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 22

यदि किसी द्विघात ग्राफ का शीर्ष ((3,-4)) है और वह ऊपर की ओर खुलता है, तो वास्तविक शून्यकों की संख्या क्या होगी?

If a quadratic graph has vertex ((3,-4)) and opens upward, what will be the number of real zeroes?

Explanation opens after your attempt
Correct Answer

C. दोTwo

Step 1

Concept

The vertex is below the (x)-axis and the graph opens upward, so it cuts the (x)-axis twice. Tip: check vertex height and opening direction together.

Step 2

Why this answer is correct

The correct answer is C. दो / Two. The vertex is below the (x)-axis and the graph opens upward, so it cuts the (x)-axis twice. Tip: check vertex height and opening direction together.

Step 3

Exam Tip

शीर्ष (x)-अक्ष के नीचे है और ग्राफ ऊपर खुलता है, इसलिए वह (x)-अक्ष को दो बार काटेगा। टिप: शीर्ष की ऊँचाई और खुलने की दिशा साथ देखें।

Question 8/9 Easy Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 23

यदि किसी परवलय का शीर्ष ((-2,0)) पर है और वह (x)-अक्ष को वहीं छूता है, तो शून्यक क्या होगा?

If the vertex of a parabola is at ((-2,0)) and it touches the (x)-axis there, what is the zero?

Explanation opens after your attempt
Correct Answer

A. (-2)

Step 1

Concept

The parabola meets the (x)-axis only at ((-2,0)). Hence its real zero is (-2).

Step 2

Why this answer is correct

The correct answer is A. (-2). The parabola meets the (x)-axis only at ((-2,0)). Hence its real zero is (-2).

Step 3

Exam Tip

परवलय (x)-अक्ष से केवल ((-2,0)) पर मिलता है। इसलिए उसका वास्तविक शून्यक (-2) है।
