यदि बहुपद का ग्राफ (x)-अक्ष को चार अलग बिंदुओं पर काटता है तो डिग्री के बारे में कौन सा कथन सही है?
If the graph of a polynomial cuts the (x)-axis at four distinct points, which statement about its degree is correct?
#degree
#maximum-zeroes
#polynomial
A डिग्री कम से कम (4) होगी / The degree is at least (4)
B डिग्री ठीक (2) होगी / The degree is exactly (2)
C डिग्री (1) हो सकती है / The degree may be (1)
D डिग्री शून्य होगी / The degree will be zero
Explanation opens after your attempt
Correct Answer
A. डिग्री कम से कम (4) होगी / The degree is at least (4)
Step 1
Concept
Four distinct real zeroes need degree at least four. The number of zeroes cannot exceed the degree.
Step 2
Why this answer is correct
The correct answer is A. डिग्री कम से कम (4) होगी / The degree is at least (4). Four distinct real zeroes need degree at least four. The number of zeroes cannot exceed the degree.
Step 3
Exam Tip
चार अलग वास्तविक शून्यक के लिए डिग्री कम से कम चार चाहिए। शून्यकों की संख्या डिग्री से अधिक नहीं होती।

यदि (p(5)\neq 0), तो (5) के बारे में क्या कहा जाएगा?
If (p(5)\neq 0), what can be said about (5)?
#not-zero
#value-test
#polynomial
#easy
A (5) शून्यक नहीं है / (5) is not a zero
B (5) शून्यक है / (5) is a zero
C (5) हमेशा दोहरा शून्यक है / (5) is always a repeated zero
D जानकारी अपूर्ण है / Information is incomplete
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।

Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 22
किस बहुपद का ग्राफ (x)-अक्ष को (x=0) पर काटेगा?
Which polynomial graph will cut the (x)-axis at (x=0)?
#condition-for-zero
#origin
#x-axis
#polynomial
A जिसके लिए (p(0)=0) / One for which (p(0)=0)
B जिसके लिए (p(0)=5) / One for which (p(0)=5)
C जिसके लिए (p(1)=0) / One for which (p(1)=0)
D जिसके लिए (p(-1)=1) / One for which (p(-1)=1)
Explanation opens after your attempt
Correct Answer
A. जिसके लिए (p(0)=0) / One for which (p(0)=0)
Step 1
Concept
To cut the (x)-axis at (x=0), the (y)-value must be (0). Hence (p(0)=0) is required.
Step 2
Why this answer is correct
The correct answer is A. जिसके लिए (p(0)=0) / One for which (p(0)=0). To cut the (x)-axis at (x=0), the (y)-value must be (0). Hence (p(0)=0) is required.
Step 3
Exam Tip
(x=0) पर (x)-अक्ष से कटने के लिए (y=0) होना चाहिए। इसलिए (p(0)=0) होना जरूरी है।

Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 22
यदि रेखा (y=2x-6) (x)-अक्ष को काटती है, तो संबंधित रैखिक बहुपद का शून्यक क्या है?
If the line (y=2x-6) cuts the (x)-axis, what is the zero of the related linear polynomial?
#linear-graph
#x-intercept
#zero
#polynomial
A (3)
B (-3)
C (6)
D (-6)
Explanation opens after your attempt
Step 1
Concept
On the (x)-axis, (y=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, (y=0), so (2x-6=0) gives (x=3). This is the graphical zero.
Step 3
Exam Tip
(x)-अक्ष पर (y=0), इसलिए (2x-6=0) से (x=3) मिलता है। यही ग्राफीय शून्यक है।
