यदि किसी द्विघात समीकरण के लिए (D=49) है तो उसके वास्तविक मूलों की प्रकृति क्या होगी?
If (D=49) for a quadratic equation, what will be the nature of its real roots?
Explanation opens after your attempt
Correct Answer
A. दो भिन्न वास्तविक मूलTwo distinct real roots
Concept
Since (D=49>0), two distinct real roots will be obtained. When (D>0), the roots are different.
Why this answer is correct
The correct answer is A. दो भिन्न वास्तविक मूल / Two distinct real roots. Since (D=49>0), two distinct real roots will be obtained. When (D>0), the roots are different.
Exam Tip
क्योंकि (D=49>0) है इसलिए दो भिन्न वास्तविक मूल मिलेंगे। (D>0) होने पर मूल अलग अलग होते हैं।
