Question 1/2
Easy Mathematics
Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 23
यदि ग्राफ (x)-अक्ष को ((10,0)) पर काटता है, तो कौन-सा कथन सही है?
If a graph cuts the (x)-axis at ((10,0)), which statement is correct?
#x-intercept
#zero
#coordinate
#graph
A (10) शून्यक है / (10) is a zero
B (0) शून्यक है / (0) is a zero
C (-10) शून्यक है / (-10) is a zero
D (10) स्थिर पद है / (10) is the constant term
Explanation opens after your attempt
Correct Answer
A. (10) शून्यक है / (10) is a zero
Step 1
Concept
The (x)-coordinate of the intersection point is (10). Therefore (10) is a zero of the polynomial.
Step 2
Why this answer is correct
The correct answer is A. (10) शून्यक है / (10) is a zero. The (x)-coordinate of the intersection point is (10). Therefore (10) is a zero of the polynomial.
Step 3
Exam Tip
कटाव बिंदु का (x)-निर्देशांक (10) है। इसलिए (10) बहुपद का शून्यक है।

Question 2/2
Easy Mathematics
Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 22
यदि (p(a)=0), तो ग्राफ किस बिंदु से अवश्य गुजरेगा?
If (p(a)=0), through which point must the graph pass?
#general-zero
#coordinate
#graph
#polynomials
A ((a,0))
B ((0,a))
C ((a,a))
D ((-a,0))
Explanation opens after your attempt
Correct Answer
A. ((a,0))
Step 1
Concept
(p(a)=0) means (y=0) at (x=a). Therefore the graph passes through ((a,0)).
Step 2
Why this answer is correct
The correct answer is A. ((a,0)). (p(a)=0) means (y=0) at (x=a). Therefore the graph passes through ((a,0)).
Step 3
Exam Tip
(p(a)=0) का अर्थ है (x=a) पर (y=0)। इसलिए ग्राफ ((a,0)) से गुजरेगा।
