Question 1/3
Expert Mathematics
Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 24
यदि (p(x)=2x-2-8) है तो ग्राफ (x)-अक्ष को किन (x)-मानों पर काटेगा?
If (p(x)=2x-2-8), at which (x)-values will the graph cut the (x)-axis?
Explanation opens after your attempt
Correct Answer
A. (-2) और (2)/(-2) and (2)
Step 1
Concept
From \(2x^2-8=0\), \(x^2=4\). Hence the zeroes are (-2) and (2).
Step 2
Why this answer is correct
The correct answer is A. (-2) और (2) / (-2) and (2). From \(2x^2-8=0\), \(x^2=4\). Hence the zeroes are (-2) and (2).
Step 3
Exam Tip
\(2x^2-8=0\) से \(x^2=4\) मिलता है। इसलिए शून्यक (-2) और (2) हैं।

Question 2/3
Expert Mathematics
Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 24
यदि (p(x)=x-2-2x-8) है तो ग्राफ (x)-अक्ष को किन बिंदुओं पर मिलेगा?
If (p(x)=x-2-2x-8), at which points will the graph meet the (x)-axis?
Explanation opens after your attempt
Correct Answer
A. ((-2,0)) और ((4,0))/((-2,0)) and ((4,0))
Step 1
Concept
(x-2-2x-8=(x-4)(x+2)). So the graph meets the (x)-axis at (x=4) and (x=-2).
Step 2
Why this answer is correct
The correct answer is A. ((-2,0)) और ((4,0)) / ((-2,0)) and ((4,0)). (x-2-2x-8=(x-4)(x+2)). So the graph meets the (x)-axis at (x=4) and (x=-2).
Step 3
Exam Tip
(x-2-2x-8=(x-4)(x+2)) है। अतः (x=4) और (x=-2) पर ग्राफ (x)-अक्ष से मिलेगा।

Question 3/3
Expert Mathematics
Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 24
यदि (p(x)=x-2-9) है तो इसका ग्राफ (x)-अक्ष को किन बिंदुओं पर काटेगा?
If (p(x)=x-2-9), at which points will its graph cut the (x)-axis?
Explanation opens after your attempt
Correct Answer
A. ((-3,0)) और ((3,0))/((-3,0)) and ((3,0))
Step 1
Concept
Solving \(x^2-9=0\) gives \(x=\pm3\). Zeroes appear on the (x)-axis as ((x,0)).
Step 2
Why this answer is correct
The correct answer is A. ((-3,0)) और ((3,0)) / ((-3,0)) and ((3,0)). Solving \(x^2-9=0\) gives \(x=\pm3\). Zeroes appear on the (x)-axis as ((x,0)).
Step 3
Exam Tip
\(x^2-9=0\) से \(x=\pm3\) मिलता है। शून्यक हमेशा (x)-अक्ष पर ((x,0)) रूप में दिखते हैं।
