Question 1/2
Hard Mathematics
Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 22
यदि किसी ग्राफ पर (p(-5)>0), (p(-2)=0), (p(1)<0), (p(6)=0) है, तो दिए गए मानों में शून्यकों का योग क्या है?
If on a graph (p(-5)>0), (p(-2)=0), (p(1)<0), (p(6)=0), what is the sum of the zeroes among the given values?
Explanation opens after your attempt
Step 1
Concept
The given zeroes are (-2) and (6), so the sum is (4). Tip: take only the (x)-values where (p(x)=0).
Step 2
Why this answer is correct
The correct answer is A. (4). The given zeroes are (-2) and (6), so the sum is (4). Tip: take only the (x)-values where (p(x)=0).
Step 3
Exam Tip
दिए गए शून्यक (-2) और (6) हैं, इसलिए योग (4) है। टिप: केवल (p(x)=0) वाले (x)-मान लें।

Question 2/2
Medium Mathematics
Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 22
तालिका में (p(-2)=6), (p(1)=0), (p(3)=-4) और (p(5)=0) है। दिए गए मानों से कौन से शून्यक मिलते हैं?
In a table (p(-2)=6), (p(1)=0), (p(3)=-4) and (p(5)=0). Which zeroes are obtained from the given values?
Explanation opens after your attempt
Correct Answer
B. (1) और (5)/(1) and (5)
Step 1
Concept
Zeroes are the (x)-values for which (p(x)=0). Tip: find zero (y)-values in the table.
Step 2
Why this answer is correct
The correct answer is B. (1) और (5) / (1) and (5). Zeroes are the (x)-values for which (p(x)=0). Tip: find zero (y)-values in the table.
Step 3
Exam Tip
शून्यक वही (x)-मान हैं जिन पर (p(x)=0) है। टिप: तालिका में शून्य (y)-मान खोजें।
