Question 1/26 Expert Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 24

यदि बहुपद का ग्राफ (x)-अक्ष को \(\frac{1}{2}\) पर छूता है तो कौन सा कथन सही है?

If the graph of a polynomial touches the (x)-axis at \(\frac{1}{2}\), which statement is correct?

Explanation opens after your attempt
Correct Answer

A. \(\frac{1}{2}\) शून्यक है\(\frac{1}{2}\) is a zero

Step 1

Concept

A zero can be a fraction and touching is enough. The key point is (p\left\(\frac{1}{2}\right\)=0).

Step 2

Why this answer is correct

The correct answer is A. \(\frac{1}{2}\) शून्यक है / \(\frac{1}{2}\) is a zero. A zero can be a fraction and touching is enough. The key point is (p\left\(\frac{1}{2}\right\)=0).

Step 3

Exam Tip

शून्यक भिन्न भी हो सकता है और छूना पर्याप्त है। जरूरी बात (p\left\(\frac{1}{2}\right\)=0) है।

Question 2/26 Expert Mathematics Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 24

यदि (p(x)=x-2-6x+9) है तो ग्राफ (x)-अक्ष को कैसे मिलेगा?

If (p(x)=x-2-6x+9), how will the graph meet the (x)-axis?

Explanation opens after your attempt
Correct Answer

A. ((3,0)) पर छुएगाIt will touch at ((3,0))

Step 1

Concept

(x-2-6x+9=(x-3)2), so (3) is a repeated zero. A repeated zero appears as touching on the graph.

Step 2

Why this answer is correct

The correct answer is A. ((3,0)) पर छुएगा / It will touch at ((3,0)). (x-2-6x+9=(x-3)2), so (3) is a repeated zero. A repeated zero appears as touching on the graph.

Step 3

Exam Tip

(x-2-6x+9=(x-3)2) है इसलिए शून्यक (3) दोहराया है। दोहराया शून्यक ग्राफ में छूने जैसा दिखता है।

Explanation opens after your attempt
Correct Answer

A. ((-2,0)) पर छुएगाIt will touch at ((-2,0))

यदि ग्राफ (x=-2) पर (x)-अक्ष को पार करता है और (x=3) पर केवल छूता है, तो अलग वास्तविक शून्यक कौन से हैं?

If a graph crosses the (x)-axis at (x=-2) and only touches it at (x=3), what are the distinct real zeroes?

Explanation opens after your attempt
Correct Answer

C. (-2) और (3)(-2) and (3)

Step 1

Concept

Both crossing and touching give (p(x)=0). Tip: write both (x)-values as distinct zeroes.

Step 2

Why this answer is correct

The correct answer is C. (-2) और (3) / (-2) and (3). Both crossing and touching give (p(x)=0). Tip: write both (x)-values as distinct zeroes.

Step 3

Exam Tip

पार करना और छूना दोनों (p(x)=0) देते हैं। टिप: अलग शून्यक में दोनों (x)-मान लिखें।
