Quadratic Equations Nature of Roots Class 10 Level 37
समीकरण \(2x^2+8=0\) के मूलों की प्रकृति क्या होगी?
What will be the nature of roots of \(2x^2+8=0\)?
Explanation opens after your attempt
Correct Answer
A. वास्तविक मूल नहीं/no real roots
Step 1
Concept
(D=02-4(2)(8)=-64<0). Therefore the equation will have no real roots.
Step 2
Why this answer is correct
The correct answer is A. वास्तविक मूल नहीं / no real roots. (D=02-4(2)(8)=-64<0). Therefore the equation will have no real roots.
Step 3
Exam Tip
(D=02-4(2)(8)=-64<0) है। इसलिए समीकरण के वास्तविक मूल नहीं होंगे।

समीकरण \(4x^2-1=0\) के मूल कैसे होंगे?
How will the roots of \(4x^2-1=0\) be?
Explanation opens after your attempt
Correct Answer
A. दो वास्तविक और असमान/two real and distinct
Step 1
Concept
(D=02-4(4)(-1)=16>0). Hence two distinct real roots will be obtained.
Step 2
Why this answer is correct
The correct answer is A. दो वास्तविक और असमान / two real and distinct. (D=02-4(4)(-1)=16>0). Hence two distinct real roots will be obtained.
Step 3
Exam Tip
(D=02-4(4)(-1)=16>0) है। इसलिए दो असमान वास्तविक मूल मिलेंगे।

समीकरण \(x^2+9=0\) के लिए सही विकल्प चुनिए।
Choose the correct option for \(x^2+9=0\).
Explanation opens after your attempt
Correct Answer
A. वास्तविक मूल नहीं/no real roots
Step 1
Concept
Here (D=02-4(1)(9)=-36<0). Therefore there are no real roots.
Step 2
Why this answer is correct
The correct answer is A. वास्तविक मूल नहीं / no real roots. Here (D=02-4(1)(9)=-36<0). Therefore there are no real roots.
Step 3
Exam Tip
यहां (D=02-4(1)(9)=-36<0) है। इसलिए वास्तविक मूल नहीं हैं।
