Question 1/7 Expert Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 23

यदि (p(x)=11(x+5)2(x-14)) है, तो ग्राफ कितने अलग बिंदुओं पर (x)-अक्ष से मिलेगा और कौन सा बिंदु स्पर्श होगा?

If (p(x)=11(x+5)2(x-14)), at how many distinct points will the graph meet the (x)-axis and which point will be a touching point?

Explanation opens after your attempt
Correct Answer

A. दो बिंदु, (x=-5) पर स्पर्शTwo points, touching at (x=-5)

Step 1

Concept

The zeroes are (-5) and (14), and ((x+5)2) causes touching at (-5). Tip: the outside (11) does not change the zeroes.

Step 2

Why this answer is correct

The correct answer is A. दो बिंदु, (x=-5) पर स्पर्श / Two points, touching at (x=-5). The zeroes are (-5) and (14), and ((x+5)2) causes touching at (-5). Tip: the outside (11) does not change the zeroes.

Step 3

Exam Tip

शून्यक (-5) और (14) हैं तथा ((x+5)2) के कारण (-5) पर स्पर्श है। टिप: बाहरी (11) शून्यक नहीं बदलता।

Question 6/7 Medium Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 24

यदि (p(x)=(x+3)(x-1)2) है तो ग्राफ (x)-अक्ष से कितने अलग बिंदुओं पर मिलेगा?

If (p(x)=(x+3)(x-1)2), at how many distinct points will the graph meet the (x)-axis?

Explanation opens after your attempt
Correct Answer

B. दोTwo

Step 1

Concept

The zeroes are (-3) and (1), so there are two distinct meeting points. Tip: count the repeated zero (1) only once for distinct points.

Step 2

Why this answer is correct

The correct answer is B. दो / Two. The zeroes are (-3) and (1), so there are two distinct meeting points. Tip: count the repeated zero (1) only once for distinct points.

Step 3

Exam Tip

शून्यक (-3) और (1) हैं, इसलिए दो अलग बिंदु मिलेंगे। टिप: दोहराए हुए शून्यक (1) को अलग गिनती में एक बार गिनें।

Question 7/7 Easy Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 23

यदि ग्राफ (x)-अक्ष को ((m,0)) और ((n,0)) पर काटता है, जहाँ \(m\neq n\), तो वास्तविक शून्यकों की संख्या क्या होगी?

If a graph cuts the (x)-axis at ((m,0)) and ((n,0)), where \(m\neq n\), how many real zeroes will it have?

Explanation opens after your attempt
Correct Answer

A. दोTwo

Step 1

Concept

Two distinct intersection points give two distinct real zeroes. Here the zeroes will be (m) and (n).

Step 2

Why this answer is correct

The correct answer is A. दो / Two. Two distinct intersection points give two distinct real zeroes. Here the zeroes will be (m) and (n).

Step 3

Exam Tip

दो अलग कटाव बिंदु दो अलग वास्तविक शून्यक देते हैं। यहाँ शून्यक (m) और (n) होंगे।
