What will be the nature of roots of (2x^2+5x-12=0)?द्विघात समीकरण (2x^2+5x-12=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=5^2-4\cdot2\cdot(-12)=121), so there are two distinct real roots. In exams, (D=121) is also a positive perfect square.यहां (D=5^2-4\cdot2\cdot(-12)=121), इसलिए दो भिन्न वास्तविक मूल हैं। परीक्षा में (D=121) धनात्मक पूर्ण वर्ग भी है।
