What will be the nature of roots of (7x^2+2x-3=0)?द्विघात समीकरण (7x^2+2x-3=0) के मूलों की प्रकृति क्या होगी?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Two distinct real rootsदो भिन्न वास्तविक मूल
Here (D=2^2-4\cdot7\cdot(-3)=88), so (D>0). In exams, when (c) is negative, (D) can often become positive.यहां (D=2^2-4\cdot7\cdot(-3)=88), इसलिए (D>0)। परीक्षा में (c) ऋणात्मक हो तो (D) अक्सर धनात्मक हो सकता है।
